Heating furnace structure

Abstract

The invention provides a heating furnace structure applied to the field of steel and iron smelting equipment. The heating furnace structure comprises a furnace body (1), wherein the furnace body (1) adopts a hollow structure; a furnace mouth (2) is formed in the furnace body (1); a furnace door (3) is arranged outside the furnace mouth (2); a telescopic part (4) is arranged on the furnace body (1); one end of a chain (5) is connected with the telescopic part (4); the other end of the chain (5) is connected with the furnace door (3); the telescopic part (4) adopts a structure capable of driving the furnace door (3) to lift through the chain (5); a guard plate (4) is arranged on the furnace door (3). The heating furnace structure of the invention has the advantages that the structure is simple; the problem that flame in the furnace body burns out the chain outside the furnace body and furnace parts outside the furnace body can be effectively eliminated; the phenomenon that the furnace door cannot be opened as well as a production accident resulting in a halt in production can be avoided; the production efficiency is improved effectively; the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of iron and steel smelting equipment, and more specifically relates to a heating furnace structure. Background technique [0002] The structure of the heating furnace is that the telescopic parts drive the furnace door to open and close through the chain. The main function is that when the slab processed in the furnace body of the heating furnace needs to pass through, the furnace door opens; after the slab passes through, the furnace door closes to maintain the temperature inside the furnace body. It is pressed against the inside of the furnace body and acts according to the control requirements to play a role in the smooth flow of production. However, the existing heating furnace structure has the following problems: 1) The temperature in the heating furnace is above 1000°C, and the furnace adopts micro-pressure control. When the furnace door is opened, the flame in the furnace will come out, and the chain and trans...

Problems solved by technology

However, the existing heating furnace structure has the following problems: 1) The temperature in the heating furnace is above 1000°C, and the furnace adopts micro-pressure control. When the furnace door is opened, the flame in the furnace will come out, and the chain and transmission equipment will be burned. chain break

3) Due to high temperature burning, the sealing ring of the hydraulic cylinder ages quickly, causing the hydraulic cylinder to leak oil and cannot work normally

4) The above reasons lead to frequent breakage of the furnace door chain and frequent oil leakage of the hydraulic cylinder, resulting in the failure of the furnace door to open normally, resulting in interruption of production and continuous casting stoppage
