Control system and method for automatically pushing steel into furnace of steel pushing type stepping heating furnace

Abstract

The invention discloses a control system and method for automatically pushing steel into a furnace of the steel pushing type stepping heating furnace. The method comprises the following steps of waiting for steel pushing after a blank is centered at a blank waiting station; sending out a furnace door opening prompt if a stepping beam is in a lower position and an empty space in the furnace meets asteel pushing distance; opening a furnace door to a high position based on a furnace door opening command, and sending out a steel pushing prompt based on a position signal of the opened furnace door; pushing, by a steel pushing machine in a work waiting station based on a steel pushing command, the blank to advance to push the blank on a conveying roller way onto a fixing beam in the furnace; sending a reset command to the steel pushing machine after the steel pushing machine reaches the target position, and retracting the steel pushing machine to the work waiting station; and sending out afurnace door closing prompt after the steel pushing machine retracts to the work waiting station, performing, by the furnace door based on a furnace door closing command, closing action till the furnace door is completely closed. The furnace door is in an opened state only in the process of pushing the steel into the furnace, and the furnace door is in a closed state in the other time, so that theheat efficiency loss is greatly reduced.

Description

Technical field [0001] The present invention belongs to the technical field of walking heating furnaces. More specifically, the present invention relates to a control system and method for automatically pushing steel into the furnace of a pushing steel walking heating furnace. Background technique [0002] The steel loading design of the walking heating furnace is generally two types: the end steel entering the furnace and the pushing steel entering the furnace. The pushing steel entering the furnace is designed with a transition table synchronized with the walking mechanism. The transition table is located between the roller table and the furnace. Between the walls, that is, located outside the furnace, the fixed beams and movable beams in the furnace of the walking mechanism installed on the transition table extend, but are not designed for water beams, but are just a set of steel structure frames; when working, the blanks are pushed by the steel pusher The upper transition pla...

[0002] The steel loading design of the walking heating furnace is generally two types: end steel feeding into the furnace and pushing steel into the furnace. A section of transition bench synchronized with the stepping mechanism is designed at the furnace feeding end of the push steel walking furnace. The transition bench is located between the roller table and the furnace. Between the walls, that is, outside the furnace, the fixed beams and movable beams in the furnace are extended by the stepping mechanism installed on the transition platform, but it is not a water beam design, but a set of steel structure frames; when working, the billet is pushed by the steel pusher The upper transitional platform relies on the movable part of the transitional platform and the fixed cooperation to transport the billet to the furnace according to the running track of the stepping mechanism "up-forward-down-back". The stepping mechanism of the transitional platform and the walking beam is segmented Due to the transitional platform running with the stepping mechanism during production, the feed furnace door cannot fall and is in a normally open state, resulting in loss of thermal efficiency, affecting energy saving and thermal efficiency, and easily causing cold air to be sucked in, affecting the furnace. pressure control
