Abstract

The invention relates to a heating furnace and particularly relates to a two-section bidirectional energy-saving walking beam heating furnace comprising a heating furnace body. The heating furnace body is internally provided with two parallel furnace cavities, namely a soaking heating cavity and an insulation-heating cooling cavity, and the two furnace cavities are respectively and internally provided with a stepping mechanism; a roller in a furnace is arranged between the two furnace cavities; the discharge hole of the soaking heating cavity is connected with a rolling mill; the feed hole of the insulation-heating cooling cavity is connected with a billet cooling bed storehouse; and a heating device is arranged in the insulation-heating cooling cavity; the charge hole of the heating furnace body is positioned between the two furnace cavities and is in a same center line with the roller in the furnace. The walking beam heating furnace disclosed by the invention is divided into the two related sections with obviously different functions, billets in a production state can flexibly run in a unidirectional manner and a bidirectional manner, and the quick and optimized heating of the hot billets can be completed in the soaking heating section by virtue of a heating process.

Description

A kind of two-part bi-directional energy-saving walking beam reheating furnace
Technical field
the present invention relates to a kind of process furnace, specifically a kind of two-part bi-directional energy-saving walking beam reheating furnace.
Background technology
large-scale walking beam process furnace is that Steel Complex connect the crucial thermal technology's heating installation between steel-making continuous casting machine and the steel rolling milling train; The hot base (or cold base) that generally comes out from continuous caster all gets into from the stove tail of walking beam reheating furnace; Steel billet, is sent into milling train then and is rolled from the burner tapping in the qualified back of stove internal heating.Mainly there is following problems in this heating process pattern:
are 1. because the difference on continuous caster and the milling train rhythm of production causes walking beam reheating furnace can not realize full hot-loading and hot-conveying.When the continuous caster direct motion, milling train is eaten, and must have the portion of hot base to roll off the production line, and wastes energy; When continuous caster had an accident low yield, the hot base of milling train was not enough again, even all ate cold base, had both made the process furnace full load operation, and its output, quality all reduce.This simple process of traditional thinking mode arranges that above-mentioned unmatched phenomenon occurring is inevitable.
More frequent cold and hot loading in mixture adopted in 2. walking beam reheating furnace, not only can not guarantee heating quality, and waste the contained residual heat resources of hot continuously cast material greatly, occurs the heating accident easily.In order to guarantee cold base heating quality and output, certainly will significantly increase the heating efficiency of stove, increase construction investment.And when stove was eaten hot base, process furnace was in serious low load with strong power state again, caused the energy dissipation of another kind of form.
Summary of the invention
the object of the present invention is to provide a kind of two-part bi-directional energy-saving walking beam reheating furnace, solve the above problems.
the technical solution adopted for the present invention to solve the technical problems is: a kind of two ends bi-directional energy-saving walking beam reheating furnace; Comprise the process furnace body; It is characterized in that, be provided with two furnace chambers arranged side by side in the described process furnace body, be respectively soaking heating chamber and insulation heating cooling chamber; Be respectively equipped with a cover stepping mechanism in two furnace chambers, between two furnace chambers, also be provided with the furnace rolls road; The discharge port of described soaking heating chamber links to each other with milling train; The feed opening of described insulation heating cooling chamber links to each other with steel billet cold bed storehouse; Also be provided with heating unit in the insulation heating cooling chamber, the feeding mouth of described process furnace body between two furnace chambers with the furnace rolls road on same medullary ray.
the invention has the beneficial effects as follows: be divided into visibly different relevant two sections of effect to walking beam reheating furnace; Looking the production status steel billet can unidirectional two-way flexible operation; Hot steel billet is accomplished the rapid Optimum heating of heating process in the soaking heating zone; Steel billet is realized three kinds of functions respectively at insulation heating cooling section, that is: insulation, the cooling in the milling train accident during basic natural labor and withdrawing from, and the benefit in the continuous caster accident is gone into the steel billet heating.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among figure: 1 process furnace body, 2 soaking heating chambers, 3 insulation heating cooling chambers, 4 furnace rolls roads, 5 heating units, 6 stepping mechanisms.
Embodiment
are as shown in Figure 1; A kind of two-part bi-directional energy-saving walking beam reheating furnace; Comprise process furnace body 1, be provided with two furnace chambers arranged side by side in the described process furnace body 1, be respectively soaking heating chamber 2 and insulation heating cooling chamber 3; Be respectively equipped with a cover stepping mechanism 6 in two furnace chambers, between two furnace chambers, also be provided with furnace rolls road 4; The discharge port of described soaking heating chamber 2 links to each other with milling train; The feed opening of described insulation heating cooling chamber 3 links to each other with steel billet cold bed storehouse; Also be provided with heating unit 5 in the insulation heating cooling chamber 3, the feeding mouth of described process furnace body 1 between two furnace chambers with furnace rolls road 4 on same medullary ray.
are sent on the furnace rolls road 4 and the warp location from the hot base that continuous caster comes out from process furnace body 1 intermediary feeding mouth, and during hot continuously cast material and milling train direct motion at this moment, the workman can directly send hot continuously cast material into soaking heating chamber 2; The workman can directly send hot continuously cast material into insulation heating cooling chamber 3 during not direct motion.Again when continuous caster is supplied hot base and is baffled because of a variety of causes; The workman will be incubated the portion of hot base that stores in the heating cooling chamber 3 and send in the soaking heating chamber 2; This moment is if can't satisfy the needs of milling train; Just mend separately into the cold continuously cast bloom of part and get into this chamber, launch the heating unit 5 that is provided with in advance simultaneously in this chamber, the temperature levels when finally making cold continuously cast bloom reach the hot continuously cast material direct motion at this place, chamber through the feed opening of insulation heating cooling chamber 3 stove tails.Can guarantee to heat soaking chamber 2 like this and have the consistent relatively hot continuously cast material of temperature levels, make process furnace body 1 be at full capacity heating condition rationally, guarantee the operating mass of heating installation.Here insulation heating cooling chamber 3 has three effects, is applicable to different operating modes respectively, and the insulation operating mode mainly is applicable in the ordinary production, solves the minor amount difference of continuous caster and rolling mill; Heating cycle mainly is applicable to when hot continuously cast material is under-supply need replenish the cold base of part in addition from this chamber afterbody; The cooling operating mode mainly is applicable to when milling train its output of accident occurs and seriously reduces, the portion of hot base from this chamber in advance slowly after the cooling corresponding again export in the steel billet cold bed storehouse that insulation heating cooling chamber 3 stove tails are provided with temporary
