The Alteration For Slab Caster Grease Lubrication Auto Control System In Xinsteel

The lubrication of machine equipments is a key job, reasonably apply to lubricate technique, thus guarantee healthily circulation of the Slab Caster equipments, which is movement foundation of the steel metallurgy industrial normal. Currently, the domestic lubrication system of Slab Caster equipments adopt more the oil spirit lubrication system and grease lubricate system, the grease lubricates system much adoption double the line type concentrate lubricates system and pass-into type concentration lubrication system, artificial lubricate still at broadly applied.These lubricate technique usually result in shortage and surfeit of lubricant, and break down order and don't easily discover to rsolve definitely.This text is about the lubricated way and control system that carried on a series of improvement design work,which combined the movement condition of lubrication system on 4# Slab Caster of Xinyu steel companies.At to domestic and international connect development present condition and lubrication present condition of Slab Caster go deep into analytical foundation up, with 4# Slab Caster of Xinsteel grease lubricate system for research object, aim at 4# Slab Caster original double of lines type concentration lubricate the system break down multifarious, the equipments service life is low, bearings damage much etc. blemish, as to it's lubricate system to carry on a reformation.Reformation of lubrication system according to the characteristics of Slab Caster equipments, lubricate request and standard, precision of measure oil control, in fixed time the lubricate, long distance supervision and control concentrate to arrive together, made to lubricate task to carry out automatic control and network supervision.Well make use of a programmable logic controller technique, do a detailed record to occurrence location and occurrence reason of breakdown;Pass human-machine interface(HMI) and superior machine, the hint maintenance personnel carries on correct check and fix maintenance in time;through the adoption to the technique of electromagnetism oil machine and capacity-type flowmeter to carry on calculating the grease amount of oil in succession, thus carry out controllability of lubricant amount.The lubrication system after reforming not only overcomes originally all shortage, but also controls a technique with modern and spread a feeling machine technique, calculator technique to well combine and carry out each lubrication to order press need, press enactment quantity to the oil, automatically examination lubricate system break down, record lubricate the system measure for oil each time,which at physically applied in, is effectively raised the accuracy and service life of fan-shaped segment, thus raised slabi quality, lowered production cost, expanded the existence space of business enterprise, therefore this text has very high practical value to the aspect of lubrication system reformation on Slab Caster equipments.
