Abstract

The invention discloses a shaping heat treatment combining process. The shaping heat treatment combining process comprises the following steps that firstly, a blank is prepared, the material and specification of a steel strip to be rolled are selected, and then the blank is uncoiled and fed into looper rolls to be ready for cleaning; the head end of the reeled-off steel strip is fed into the looper rolls distributed in a crossed mode and sequentially wound around the circumferential outer walls of all the looper rolls; the steel strip sent out from the looper rolls passes through the outer wall of the bottom end of a limiting roll in a pickling tank, then is wound around the outer wall of another limiting roll at the other end of the bottom of the tank and afterwards is drawn out; the steel strip pickled in the pickling tank passes through a new looper roll and enters a continuous rolling unit to be subjected to thickness rolling adjustment; and annealing is carried out after the specification of the steel strip rolled through the cold rolling unit meets requirements. By means of the shaping heat treatment combining process, the transverse floor area can be reduced, the strip steelas long as thousands of meters can be wholly subjected to heat treatment at the same furnace temperature, and thus the uniformity of grains in the steel strip is improved, and the overall performanceof the steel strip is improved.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a forming heat treatment combined process. Background technique [0002] Heat treatment is a metal thermal processing process that heats, heats and cools metal materials in a certain medium, and controls its performance by changing the metallographic structure of the material surface or inside. The well-type heat treatment furnace equipment is a kind of Heat treatment equipment for workpiece quenching, tempering, impregnation, cleaning, etc., especially heat treatment equipment that combines two or more heat treatment processes. [0003] After retrieval, the Chinese patent authorization number is the patent of CN 202734487 U, which discloses a well-type heat treatment furnace, including a furnace body and a furnace cover on the top of the furnace body. The furnace cover is provided with a fan, but the device has no return air Circulation system, and there is no equipment ...
