Description

W-shaped fork frame for supporting gas with oxygen

Technical Field

The utility model belongs to the technical field of the iron and steel smelting technique and specifically relates to a W shape crotch that is used for gas area oxygen area to support is related to.

Background

With the rapid development of the steel-making technology, the high drawing speed of the casting machine is gradually increased from 3.0m/min to 3.5m/min, so that the requirement on the logistics production organization of the casting machine is higher and higher. The method mainly comprises the steps of burning refined coke oven gas and oxygen to cut a continuous casting blank, wherein the fire cut-off rate of a continuous casting machine of a general steel mill is 99.4%, 17.5 continuous casting machines are required to be cut by manual knife supplement on average every day, due to the fact that the time of manual cutting is random, an operator is required to pay attention to the fire cut dynamics of the casting blank on a monitor at any time, and once the continuous cutting or the casting blank lack of ribs occurs, the operator is required to rapidly make a judgment to prevent the occurrence of non-stop accidents caused by blank ejection of the casting blank.

When the gas or oxygen pressure is abnormally fluctuated or the flame cutting machine fails to cut normally, personnel under the table are needed to quickly react and adopt a cutting gun to supplement a cutter for a non-cut casting blank, and how to independently treat the potential safety hazard brought by the non-cut casting blank and the unfavorable condition of production interruption under the condition of no cooperation is a very necessary thought.

When the cutting gun is used for cutting off, the cutting gun relates to the use of a gas belt and an oxygen belt, how to prevent the burning of the gas belt and the oxygen belt by high temperature of a casting blank, plays a role in safety protection, how to achieve quick reaction and disposal under the condition of reducing manpower and material resources, reduces the accident rate, is a frequently-faced matter for field operators, causes the casting blank to be cut off when the cutting knife is untimely even in actual work, has the burning phenomenon of the gas belt and the oxygen belt of the cutting gun, and has safety control risk.
