Description

technical field [0001] The invention relates to the baking and heating technology of ladle in iron and steel enterprises and foundry enterprises. Background technique [0002] Most of the existing ladle roasters are products upgraded from the first-generation casing-type ladle roasters—regenerative ladle roasters. The basic principle is to configure two sets of combustion devices, each set of combustion devices is equipped with a ceramic honeycomb regenerator at the burner, and the regenerator absorbs and stores the heat in the flue gas after combustion. When the two sets of combustion devices work alternately, the accumulated heat is transferred to the gas and combustion air, so as to achieve the purpose of reducing gas consumption and production cost. [0003] However, the structure of the regenerative ladle roaster is complex, the four-way reversing valve is easily damaged, and the honeycomb holes of the ceramic honeycomb regenerator are easily blocked by dust and carbon...

Problems solved by technology

[0003] However, the structure of the regenerative ladle baker is complex, the four-way reversing valve is easily damaged, and the honeycomb holes of the ceramic honeycomb regenerator are easily blocked by dust and carbon particles; due to the low expansion coefficient of ceramics, repeated thermal expansion and contraction The ceramic body is easily broken, resulting in poor ventilation of gas or air, affecting production and safety; and because the heat storage process of the heat storage body is intermittent, the absorption and utilization of waste heat in the flue gas is not thorough, and there are still a large number of The waste heat of the gas is not utilized, resulting in incomplete energy saving effect of gas
