Abstract

A kind of cold-rolling equipment working roller technique for preventing bearing position into cold rolling liquid, the invention belongs to the roll designs of metallurgical technology field cold-rolling of steel plate unit, in traditional four-roller Krause mill, working roll and strip generate heat in the operation of rolling, lubrication and cooling are played the role of by injection ROLLING OIL, but one section of bearing of work can heat up to wear and break down because of lubricating oil reduction.Support roller both ends axle journal is also easily broken off.The present invention provides a kind of new steel plate cold rolling mill work roller structures thus, including work roll surface and working roll axle journal two parts, blocking solution slot is increased between described two parts, it is characterised in that the blocking solution slot of this new steel plate cold rolling mill work roller structure and symmetrical close to blocking solution ring both sides.Roll both sides end is flat type, is installed convenient for roller system.More than invention applies in actual production, and 3 times or so can be reduced to the spoilage of bearing, and the invention is simple and practicable, and energy-saving highly significant is worthy of popularization.

Description

A kind of cold-rolling equipment working roller technique for preventing bearing position into cold rolling liquid

Technical field

The invention belongs to metallurgical technology fields, are related to a kind of roll design of cold-rolling of steel plate unit, and in particular to Yi Zhongxin The new structure of type cold roll.

Background technology

In traditional four-roller Krause mill, including working roll, support roller, pressure oil cylinder and rack, no matter existing six roller Krause mill is that intermediate calender rolls are increased between the working roll of traditional 4-roller cold rolling mill and support roller, is all both ends and the axis of roll Assembling is held, there are two types of lubricating system, dry oil lubrication and fog lubrication for bearing.

Working roll and strip generate heat in the operation of rolling, and lubrication and cooling are played by injection ROLLING OIL or rolling mill compound Effect, but rolling mill compound belongs to alkalies, to the lubrication chemically reactive of bearing, causes one section of bearing of work can be because of lubrication Oil is reduced and the abrasion that heats up breaks down.Support roller both ends axle journal is also easily broken off, and the bearing on axle journal is also easy to damage.This is not only Increase use cost, and very big loss is caused since the repair that often stops production delays production.Also there is examination person using jacketed ring, add The methods of sealing ring, attempts to make up the defect, but all of no avail.

Therefore, to improve rolled products quality must to the roll of rolling equipment carry out reasonably with the innovation of essence Design and transformation.

Invention content

The purpose of the present invention is to solve the above problems that current traditional four, six roll steel plate cold-rolling mills are primarily present, and carry A kind of simple in structure, roll has been supplied to make a kind of simple and reasonable, at low cost, effect is good distribution of force new steel plate cold-rolling mill Work roller structure.

For this purpose, the present invention provides a kind of new steel plate cold rolling mill work roller structure, including work roll surface and work roll shaft Neck two parts increase blocking solution slot between described two parts, it is characterised in that：This new steel plate cold rolling mill work roller structure Blocking solution slot R>8mm, close to blocking solution ring behind>10mm.Both sides are symmetrical.The width of blocking solution slot is 2 times of blocking solution ring.

Roll both sides end is flat type, is installed convenient for roller system.More than invention applies in actual production, to bearing Spoilage can reduce by 3 times or so, and the invention is simple and practicable, energy-saving, and highly significant is worthy of popularization.

Description of the drawings

Fig. 1 is work roller structure schematic diagram, and A-A is expressed as the elevation of working roll, and the both ends for representing working roll are flat.

Claims

1. in order to solve the above problem that traditional four, six roll steel plate cold-rolling mills are primarily present at present, provide it is a kind of it is simple in structure, Roll makes a kind of simple and reasonable, at low cost, effect is good distribution of force new steel plate cold rolling mill work roller structure.

2. for this purpose, the present invention provides a kind of new steel plate cold rolling mill work roller structure, including work roll surface and working roll axle journal Two parts increase blocking solution slot between described two parts, it is characterised in that：This new steel plate cold rolling mill work roller structure Blocking solution slot R>8mm, close to blocking solution ring behind>10mm.

3. both sides are symmetrical.

4. the width of blocking solution slot is 2 times of blocking solution ring.

5. a kind of cold-rolling equipment working roller technique for preventing bearing position into cold rolling liquid, it is characterised in that：Roll both sides end For flat type, installed convenient for roller system.
