Energy-saving premixing internal combustion type blast-furnace gas steel ladle baking device

Abstract

The invention discloses an energy-saving premixing internal combustion type blast-furnace gas steel ladle baking device. The energy-saving premixing internal combustion type blast-furnace gas steel ladle baking device basically consists of a ladle cover, wherein a nozzle is installed at the center of the ladle cover, and a rocker arm and the ladle cover are connected through a positioning plate and bolts. The rocker arm, a suspension arm, a tie bar, a rotary shaft and a bearing seat form a rigid body and are connected through a steel wire rope, a winch, a fixed pulley and a pulley device. A rack is connected at the lower end of the bearing seat, and the lower end of the rack is fixed to an embedded part. Valve assemblies are sequentially installed in a pipeline system. All constitutional electrical elements, signal lines and power lines are connected to a control cabinet. The control cabinet is remotely controlled, data is transmitted to the intelligent control cabinet in a control chamber through a reticle for remote operation. The device is mechanically and electrically optimized in design, the safety performance is improved, a quick and convenient use function is achieved, the combustion efficiency is improved, and accordingly energy loss is reduced.

Description

technical field [0001] The present invention relates to a steel ladle baking device used in new construction, turnover, cold repair, drying and online rapid heating of each molten steel tank, especially for blast furnace gas / water gas gas medium with low calorific value. Specifically, it is a premixed internal combustion type ladle baking device. Background technique [0002] The iron and steel industry bears the heavy responsibility of my country's pillar industries, and its contribution rate to the country's economic growth continues to increase. At the same time, with the rapid growth of my country's economy, the constraints on energy consumption and consumption of resources have become apparent, and the contradiction between energy supply and demand has become increasingly prominent. The characteristics of high pollution and high energy consumption have also put pressure on the iron and steel industry in terms of pollution prevention, emission reduction, energy conservat...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that during the current ladle baking process, the blast furnace gas with low calorific value is not easy to ignite at normal temperature and is easy to defire; the heat dissipation of the cover is serious, and the heat preservation effect is not ideal; The problem of the required baking temperature; and the temperature measuring device cannot accurately feedback the bottom temperature of the ladle, and thus cannot accurately set the baking process according to the heating curve of the refractory material; simplify the existing regenerative ladle baker The structure reduces the maintenance workload; the existing advanced automatic control software is used to realize remote control, allowing the operator to adjust the parameters of the on-site baking device in the rest room, etc., in order to reduce the kinetic energy loss of the gas passing through the cone valve , designed as a structural model with arc bosses; in order to solve the above problems, an energy-saving premixed internal combustion blast furnace gas ladle baking device is provided
