Production Process Circulation
Loading→ Transfer the cylinder to the loading conveyor of Quenching Furnace by overhead crane→ Quenching Furnace Doorway Open→ EPT the cylinder into the Quenching Furnace speedily → Heating cylinder inside of of Quenching Furnace(In the meantime, cylinders moves slowly to stop the roller from distortion and enhance the uniformity of heating)→ Center Doorway (Warmth Insulation) Open up → Cylinders transferred rapidly to the Keeping zone of Quenching Furnace(In the meantime, cylinders moves gradually to avoid the roller from distortion and improve the uniformity of keeping)→ Right after approach time is completed → Unloading Door Open up and the cylinders are unloaded rapidly → Doorway Shut, Cylinders are transferred to the Facet Unloading EPT of Quenching Tank→ Transfer cylinders into the Quenching tank for Quenching. In the meantime, the transfer vehicle moves up and down, as to uniform the quenching media and ensure the quenching good quality → Elevate up cylinders with Transfer auto → EPT cylinders to loading conveyor of Tempering Furnace → Tempering Furnace Doorway Open up → Transfer into tempering furnace for heating(doing work sequence, Takt time, management manner are all identical as quenching furnace)→ Tempering Furnace Door Open up after the procedure time is attained → Unloading swiftly → Cylinders are transferred to Unloading conveyor, cooling down and waiting around for unloading → A single cycle is completed, Waiting.
five. Transient Equipment Introduction
5.1 Loading EPT
It is mainly developed for loading and fast convey of metal cylinder, which consi EPT of supporting bracket, roller, driving gadget, and manage device.
Help Bracket: It is made of shaped metal and steel plate and welded with each other, which provides a great visual appeal. Anchor plate is welded to the base of supporting bracket, which is fixed on to the embedded plate of basis, as to make sure the reliability and protection.
Roller Conveyor: It is produced of 20# seamless metal tube (φ159×6mm). Positioning gadget is outfitted with the roller to avoid the offset of metal cylinder and falling down throughout moving. Two finishes of roller is made of forty five# steel and machined into the shaft condition, and fastened onto the supporting bracket with the bearing. Locating bolts are geared up with the bearing to avert the roller from deviating.
Driving System: It is pushed by speed reducer through sprocket whee EPT and chains. The velocity reducer is advisable to pick MD Series helical gear redactor, made by Omiter, ZheJiang .
Driving pace is controlled by Siemens Frequency Converter that outputs signal to velocity reducer, as to accomplish the speed control of roller.
Operation terminal packing containers are geared up with each of loading and unloading conveyor, which is made up of thrust buttons like Begin, Unexpected emergency Stop, Reverse, and and many others.. The conveyor begins to work following pressed Start off.
A pair of photoelectric switches is outfitted at the end of roller conveyor. When cylinders pass by way of the conveyor, photoelectric change sends out the sign to PLC, and PLC will deliver the sign to handle the velocity reducer instantly.
Unexpected emergency Cease and Reverse are utilized beneath emergent problems.
Interlock: All driving program is interlocked with the furnace. It can not be loaded and unloaded until finally the furnace doorway opens in area.
5.2 Quenching Furnace
It is made up of furnace shell, lining, furnace door and its lifting gadget, roller conveyor, roller driving technique, entry door, combustion program, exhausting program and etc..
Furnace Shell: It is produced of steel plate and fashioned metal and welded collectively which supplies a good visual appeal (Welds height is no much less than 5mm). Outer shell is produced of fashioned steel which offers a great power.
Lining: It adopts compound construction. The lining materials is various at bottom furnace, furnace doorway, facet wall and roof.
Bottom Lining: Base of furnace shall be cleaned routinely for taking away the oxides, as a result, base liner is manufactured of mild-fat refractory bricks and aluminosilicate fiber. Refractory bricks are on the top surface area, as ease to eliminate oxides. Aluminosilicate fiber is applied in between refractory brick and steel plate for warmth insulation.
Liner of Furnace Door: It is made of heavy weight higher aluminum bricks, which is to stop the lining from being worn out.
Liner of Facet Wall and Roof: For energy saving and reduction, the insulating components, pre-compressed aluminosilicate folding blocks (Functioning temperature is far more than 1100ºC), are supplied by Yeso, which will be installed onto the facet wall and roof through the particular anchors (1Cr18Ni9).
Insulating material shall be picked based mostly on the a variety of wants and necessity, these kinds of sort of compound structure is less excess weight, much more trustworthy, much less upkeep, minimized the warmth decline.
Furnace Door and Its Lifting Method: Quenching furnace has tow temperature zones, one particular zone is heating and the EPT is holding. Middle door is created among two zones, which is produced of heat resistant ca EPT iron. Loading and unloading doorways (produced of heat resistant ca EPT iron) are developed at two ends of furnace entire body.
Furnace Doorway: Doorway and Doorway Plate are created of heat resistant castings, aluminosilicate fiber blanket shall be presented inside of insulation. These kinds of variety of construction is less distortion, considerably less bodyweight, with a longer service lifestyle and much better heat insulation.
Furnace Door Lifting System
.The furnace door is pushed by the chain and sprocket whee EPT via a velocity reducer or cylinder. The seal between furnace door and door plate is compressed by the guiding track and angle iron, as to ensure the safety and dependability. Opening and Closing of Furnace doorway is limited by a limit swap set up at facet of lifting chain.
Furnace Door Driving Pace Reducer: MD series helical gear reductor, it is outfitted with braking device.
Furnace doorway is interlocked with driving technique and heating method. In EPT words, roller conveyor can’t be loaded and unloaded until finally the furnace doorway is opened in location, and can’t be heated right up until the furnace door is closed in spot.
Roller Conveyor: It made of heat resistant ca EPT irons (Cr25Ni20Si2) and poured into the castings with φ159×20. Positioning gadget (Cr25Ni20Si2) is outfitted with roller conveyor to stop the steel cylinder from running off center. Shaft conclude is casted and set on to the metal structures with the vertical bearing. Roller is installed at the interva EPT of 800mm roughly.
Refractory and Insulating substance at two finishes of roller is stHangZhourd fiber lagging.
Best go over is movable, and hooked up to the furnace entire body with the bolts.
Enlargement will be transpired on the roller soon after heating. For driving facet, it is outfitted with finding pins for positioning and freely growth, which are fastened with bearing. For non-driving side, important slots are made and round locating bolts are adopted on the bearing, which certain the freely axial expansion and radial driving.
Driving System for Conveyor: It is pushed by a velocity reductor by means of the chain and sprocket wheels. Speed reducer is made by Omiter, ZheJiang , kind: MD sequence helical gear reductor. The braking gadget is outfitted with the velocity reducer, which can quit the motion timely.
Driving pace is managed by Siemens frequency converter, it outputs sign to pace reducer and as to control the driving pace of conveyor.
During heating, metal cylinders are executed a recurring to-and from motion in each and every heating zone to assure the services daily life of conveyor and boost the uniformity of heating. Cylinder’s motion shall be restricted by a limit change to keep it centered, which is much more precision and reliable.
A single established of photoelectric restrict swap is geared up at the heating zone and keeping zone of quenching furnace respectively, which are fixed at the two sides of furnace human body with the supporting. The cylinders can be positioned by way of the signal offered by restrict change (positioning accuracy is ≤20mm).
Obtain Door: An obtain door is created at the base of quenching furnace for removing the oxides routinely, or when the products is shut down or servicing. It is made of steel plate and aluminosilicate fiber. Steel plate is assembled on to the furnace physique with the bolts. Connecting nuts adopts wing nuts as to disassemble easily.
Sight holes are made at interva EPT of 3~4m of two side wal EPT for observing the functioning condition of workpieces inside of furnace. Hole seat is created of ca EPT iron, which gives a great seal, and far more trustworthy and safe.
