A Method of Protecting the Gear of Blast Furnace Encoder

Abstract

The invention discloses a method for protecting the gear of a blast furnace encoder. The method realizes the protection of the blast furnace encoder by means of real-time zero adjustment. Including collecting blast furnace body equipment parameters; establishing the functional relationship between the blast furnace body equipment control parameters and the current encoder scale value, that is, the current encoder zero function; establishing a blast furnace encoder zeroing process control model, which is used to describe the blast furnace The relationship between the zero scale value of the encoder and each control parameter; the zero scale value of the encoder is determined by using the zero scale value of the blast furnace encoder process control model, and the real-time zero adjustment control is performed on the current scale value of the blast furnace encoder. In the present invention, as long as the actual position of the probe is known, the control model of the present invention is used to calculate the zero position of the encoder, and the arbitrary zero adjustment of the blast furnace encoder is realized, without manual adjustment to the zero position of the encoder, saving energy. labor costs. In addition, the loss of the wheel of the encoder is reduced, and the service life of the encoder is increased.

Description

technical field [0001] The invention relates to the field of blast furnace smelting, in particular to a method for protecting a blast furnace encoder gear. Background technique [0002] The main way of blast furnace cloth is ring cloth. Ring distribution is to distribute the charge into the blast furnace in a ring shape through the horizontal rotation of the blast furnace distributor. The blast furnace distributor is the distribution equipment on the top of the blast furnace, which consists of a discharge chute, a rotating mechanism and a tilting mechanism that drive the chute to rotate horizontally and tilt vertically. Its function is to cooperate with the rotating mechanism of the feeding chute and the tilting mechanism, so that after the feeding chute reaches the preset tilting angle a, the blast furnace charge is distributed into the blast furnace in a circular shape according to the specified number of horizontal rotation rings. on the material surface.

Problems solved by technology

[0003] At present, every time the blast furnace chute, probe, and rotary distributor are inspected or maintained in blast furnace production, the encoder on it needs to be zeroed after inspection. In actual operation, it is quite difficult to adjust and fix the encoder, and the encoder must be manually adjusted. The gear is adjusted to the mechanical zero position, and the gear rotates forward for a while, and reverses for a while, which not only increases the labor cost but also increases the wear of the encoder gear, shortening the service life of the gear
