Abstract
The utility model discloses a heat treatment system for a super-thick steel plate. The heat treatment system consists of shot blasting unit equipment, heat treatment furnace equipment, a steel plate aerial fog accelerated cooling unit, a cooling bed, an online super-thick plate turnover machine, a sampling shear and a finished product making machine. The heat treatment system is characterized in that the shot blasting unit equipment is arranged in a semi-finished product receiving warehouse; a normalizing furnace and a tempering furnace of a long furnace type heat treatment furnace are arranged in parallel; the steel plate aerial fog accelerated cooling unit (NCC) is attached to the normalizing furnace; the online super-thick plate turnover machine is arranged on a check bench in an online way; a feeding and discharging roller bed of semi-finished steel plates is arranged at a cooling bed outlet; and the finished product making machine is arranged on a finished product roller bed. The heat treatment process requirements of the super-thick steel plates, such as heat treatment normalizing, normalizing and tempering, tempering and accelerated cooling of a steel grade are met. According to the heat treatment system disclosed by the utility model, the combined property of the super-thick steel plate is improved and the occupied space of the semi-finished warehouse is reduced; the online turnover of the plate is realized, the straight traveling rate of the products is increased and the requirement of the heat treatment process of the super-thick steel plate on long time is met; and the swing and roll marks of the steel plate are reduced and the surface quality of the steel plate subjected to heat treatment is ensured.
Description
Affiliated technical field
The utility model belongs to the steelmaking equipment device, is specifically related to a kind of super-thick steel plate heat treatment system
.
Technical background
China has built and has had tens at the Wide and Thick Slab production line of building.In many Wide and Thick Slab production lines, thickness is greater than the thermal treatment process of the special heavy plate of 60mm, causes because of equipment layout is improper that technical process has some setbacks, logistics is not smooth, can't satisfy the requirement of special heavy plate kind technology, causes that short distances transportation causes cost to rise in the factory.And for a kind of relatively independent special heavy plate production line, it can not accomplish the technology of corresponding operation, and must could accomplish to other places.
Special heavy plate product thermal treatment process flow process is seen Fig. 1 in the prior art.The Wide and Thick Slab apparatus for production line disposes online plate turnover and off-line plate turnover in arranging.Online plate turnover is an electrodynamic mechanical type, and turnover panel speed is fast; The off-line plate turnover is a hydraulic mechanical type, and turnover panel speed is slow; The maximum ga(u)ge of online plate turnover turnover panel is 50mm, greater than the 50mm steel plate off-line plate turnover turnover panel that can only roll off the production line.Special heavy plate off-line turnover panel inspection upper and lower surfaces causes the interim stock plug long-pending, takies semifinished product warehouse, and product craspedodrome rate is low, causes the delivery cycle long.
The utility model content
The purpose of the utility model provides a kind of super-thick steel plate heat treatment system that overcomes above-mentioned prior art weak point,
The technical scheme of the utility model: a kind of super-thick steel plate treatment production system, quickened by shot-blasting machine group equipment layout, heat treatment furnace equipment layout, steel plate aerosol that cooling unit, cold bed, online special heavy plate plate turnover, sampling are cut, finished product sign machine is formed.It is characterized in that: the ball blast unit is arranged in the rewinding semifinished product warehouse; The normalizing furnace and the tempering stove of long type of furnace heat treatment furnace are arranged side by side; NCC is attached to normalizing furnace and arranges; The online inspection stand that is arranged in of special heavy plate plate turnover; Work in-process steel plate line roller-way is up and down arranged in the cold bed outlet; Sampling is cut and is arranged in the outlet of inspection stand; Arrange the sign machine at the finished product roller-way.
The super-thick steel plate normalizing is quickened the cooling back at the cold bed air cooling, and online turnover panel inspection upper and lower surfaces is handled and indicated; Tempering after needing tempering steel plate cold bed to roll off the production line, online turnover panel inspection upper and lower surfaces is handled and is indicated.
The utility model principle of work: being arranged side by side of normalized and tempered stove, satisfy the requirement of special heavy plate normalizing, normalizing+tempering, tempering heat treatment process; The normalized and tempered stove of the long type of furnace guarantees that the special heavy plate heat-treated steel plate need not in stove, to swing, and reduces the steel plate roll marks; Quicken to arrange after the cooling unit is attached to normalizing furnace, satisfy the special heavy plate after-acceleration refrigerative requirement of coming out of the stove, reduce cooling time and reduce the cold bed area effectively; Normalizing after-acceleration cooling, the requirement that improves Cr-Mo steel and other steel special process; The layout in upper and lower material roller road, making in time rolls off the production line after normalizing+tempering process special heavy plate normalizing returns the tempering of material loading place, has reduced and has had bad luck in the workshop and the taking of semifinished product warehouse; The layout in upper and lower material roller road makes and to need the reconditioning steel plate in time to roll off the production line and return line production; The layout of online special heavy plate plate turnover has realized the online turnover panel of special heavy plate at home first, has improved the craspedodrome rate of product.
Compared with prior art, the utlity model has following advantage:
A, satisfy special heavy plate heat treatment normalizing, normalizing+tempering, tempering and steel grade thermal treatment process requirements such as quickening cooling is arranged.
B, normalized steel plate in time quicken cooling and reduce the cold bed area, have also satisfied the requirement of part steel grade special process, have improved the special heavy plate over-all properties simultaneously.
C, special heavy plate roll off the production line in time, reduce having bad luck of steel plate, reduce taking semifinished product warehouse.
D, steel plate are realized online turnover panel, have improved the craspedodrome rate of product.
The long requirement of special heavy plate thermal treatment process time is satisfied in the configuration of e, the long type of furnace, reduces the steel plate swing, reduces the steel plate roll marks, has guaranteed plate surface quality after the thermal treatment.
