Abstract
The invention relates to production line equipment for enhancing physical property of a steel member, which is used for enhancing the steel members of a large-scale steel structure building, a bridge tunnel engineering, a heavy-type machinery case or a framework; and the production line equipment comprises a preheating furnace, a mesotherm soaking pit, a gas protection furnace, a tempering furnace, a cooling chamber, a shot blast rust-removal chamber and a coating chamber. According to the invention, the manufactured steel member is automatically conveyed and passed through the furnace body by a high temperature-resistant push rod or a roller way, and is processed by the corresponding heat treatment and shot blasting treatment for enhancing the strength of the steel member, removing the rust and coating. The production line equipment for enhancing physical property of a steel member is used for enhancing the steel members of the large-scale steel structure building, the bridge tunnel engineering, the heavy-type machinery case or the framework, the yield strength of the treated low alloy steel member is increased by more than two times, the application amount of the precious metal is reduced, labor intensity and damaged environmental pollution during a whole production process can be effectively reduced, the energy saving and emission reduction can be carried out with large amplitude, and good social and economic benefits can be achieved.
Description
Technical field
The present invention relates to a kind of steel member physicals and strengthen apparatus for production line, particularly for the treatment production of the steel members such as large-scale steel building, bridge tunnel engineering, heavy-duty machinery housing or framework.Belong to special equipment technical field.
Background technology
At present steel member equipment for Heating Processing is had relatively high expectations to manpower, and workman operates in the pollution operating environments such as high temperature, poisonous, dust, noise, can cause security incident time and workman's physical and mental health occurs and affect; In addition, prior heat treatment production process operating efficiency is not high, affects steel member heat treatment performance effect, causes its physicals cannot reach perfect requirement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of steel member and strengthens by thermal treatment process again the automatic production line equipment of its physicals, to overcome above shortcomings in prior art.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
The automatic production line equipment that steel member strengthens by thermal treatment again, comprises preheating oven, middle temperature soaking pit, gas shield stove, tempering stove, cooling room, shot peening chamber, paint booth; Steel member is preheated to certain temperature with push rod or roller-way automatic transport to described preheating oven, is delivered in described middle temperature soaking pit and heats up, and make steel member keep samming, then carry out quenching heat treatment technique through described gas shield stove, refinement steel member crystal grain; Then enter and after described tempering stove heats again, enter in described cooling room coolingly, conventionally adopt air and liquid cooling; Steel member completes after above heat treatment step, has strengthened its physicals; Change steel member after physicals and enter described shot peening chamber and carry out shot peening processing, obtain certain roughness, appear the steel member of the table phase of metal true qualities, then through paint booth sprayed coating, the steel member that formation can directly be used.
The invention has the beneficial effects as follows: the manipulation of this equipment whole-course automation, reduce workman and operated in the pollution operating environments such as high temperature, poisonous, dust, noise, reduce greatly security incident generation; And improve the operation efficiency of whole heat treatment process, improved the physicals of steel member, can make the yield strength of low alloy steel member improve the above effect of twice.
