Problems solved by technology

However, the data issued by the L2 computer mainly provides operation guidance, and seldom directly controls production. Even if the data issued by the L2 computer is used to control production, it is strictly following the concept of batch blanking for feeding, often due to the gap between each batch The time interval is short, and the material cannot be weighed according to the set amount in time and automatic feeding cannot be realized

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] The feeding system equipment in the steelmaking converter generally includes: silo, vibrating feeder controlled by frequency conversion, weighing hopper (with weighing instrument), discharge valve under weighing hopper, collecting hopper, discharging valve under collecting hopper, etc. , the material is put into the converter or ladle from the silo through the above equipment. However, due to the difference in converter design, the combination of feeding equipment is slightly different. The typical combination diagram is shown in figure 1 . Among them, the combination in (a) is the form of one silo corresponding to one weighing hopper; the combination in (b) is the form of two silos corresponding to one weighing hopper; the combination in (c) is the form of three silos corresponding to one weighing hopper. The form of the bucket; (d) the comb...

Abstract

The invention discloses a control method used for a computer batch charging system of a steelmaking converter and belongs to the technical field of metallurgical automatic control. The control method comprises the following steps of: receiving a batch charging data table issued by an L2 computer by virtue of an L1-stage PLC (programmable logic controller), and distributing materials into each stock bin according to a stock bin distribution principle; and forming a primary stock bin automatic batch charging data table; according to blanking speed and blanking weight of each stock bin, judging reasonability of the stock bin automatic batch charging data table, and correcting a primary stock bin automatic batch charging data table; and decomposing material data, and forming a batch charging data table of a sub weighing system taking each weighing hopper as a main body. By adopting the control method, materials can be reasonably distributed, and utilization rate of a stock bin is increased, so as to speed up production rhythm; and normativity and stability of the batch charging system can be improved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical automatic control, and specifically relates to a control method for a computer feeding system of a steelmaking converter. Background technique [0002] All along, automatic steelmaking is generally undertaken by L1 (basic automation) and L2 (process control computer system). The input of auxiliary raw materials and alloy materials has been operated for a long time due to many uncontrollable factors such as the complex and changeable steelmaking process, the various design performances and combinations of feeding equipment manufacturers, and the variety of raw materials such as auxiliary raw materials and alloy materials. According to the experience, the personnel set the input amount on the L1 system and start the automatic vibrating material manual feeding method to realize it. However, the data issued by the L2 computer mainly provides operation guidance, and seldom directly controls prod...
