Abstract

The utility model discloses a multipurpose sample plate for the quick slot arrangement of a rolling mill roll gap, which comprises a plate body in a cuboid shape, the width of the plate body is the same as the roll gap value of a vertical rolling mill, the height of the plate body is the same as the roll gap value of a horizontal rolling mill, the end surface at one side of the plate body is fixedly connected with a handle, and the handle is arranged along the length direction of the plate body. The sample plate has a simple structure, can quickly and accurately adjust the roll gap, greatly improves the work efficiency, and reduces the labor intensity.

Description

A kind of mill roll-gap is established groove fast and is used model more

Technical field

The utility model relates to a kind of mill roll-gap to be established groove fast and uses model more, belongs to the mill roll-gap adjusting device.

Background technology

In the steel rolling production operation of rolling, the groove of milling train and red steel are in contact with one another, and certainly exist wearing and tearing for a long time.Roll and groove must be changed, otherwise can directly influence product quality after rolling certain hour and certain output.This replacing is comparatively frequent in the production, change groove about will carrying out more than 3 times every day as high-speed rod, then, in the time of when changing groove, need resetting roll gap, gap values between rollers before must guaranteeing new gap values between rollers and changing is identical, otherwise the variation of roll gap can cause the red steel dimensions that rolls out to change, and makes the overproof generation waste product of finished size.Therefore the setting of new roll gap is extremely important in the rolling process, is the technical ability that the roller must be on top of.

The establishing method of at present new roll gap is by adopting clamp to measure roll gap, measure with slide measure, carrying out the folding and unfolding of roll gap according to the size that measures then, up to adjusting to suitable gap values between rollers.And change the groove operative employee and can measure unavoidably and make mistakes because of frequent in the practical operation, the unskilled operative employee Geng Yi amount of technical ability is wrong.Therefore heap steel accident, the quality accident that causes because of intermesh determination is improper often has generation.Owing to exist the gap between milling train screwdown gear and the roll chock, roll chock can be upspring the gap is eliminated when red steel was nipped milling train in addition, can make gap values between rollers become big like this, also very easily caused production accident.

Summary of the invention

The purpose of this utility model is to provide a kind of mill roll-gap to establish groove fast and uses model more, and it is simple in structure, can adjust roll gap quickly and accurately, increases work efficiency greatly, reduces labor strength.

The purpose of this utility model is to realize like this, a kind of mill roll-gap is established groove fast and is used model more, comprise plate body, plate body is cuboid, the width of plate body is identical with the gap values between rollers of vertical mill, the height of plate body is identical with the gap values between rollers of flat milling train, affixed handle on the side end face of plate body, and handle is arranged along the length direction of plate body.

During use, design the width and the height of model according to last flat milling train and back one the needed roll gap of vertical mill, the new grooved roller seam that to change during use is adjusted to full open position, put in the middle of two grooves with the model of making by the process requirement in advance, the mill roll-gap screwdown gear is depressed, until two rolls all be pressed onto can not depress again on the model till.With the milling train counter-rotating, model is poured out again.Gap values between rollers between such two rolls is just just the same with the height of model.And in the process of two rolls pressure model, roll chock is upspring, help to eliminate the gap between bearing block and screwdown gear.

The utility model model has following characteristics: 1, be convenient to newly design the use that the mill milling roll gap is adjusted model, red the size error that shuts out after the setting guaranteed ± 0.1, and simplify the operation, save and changed groove time per pass 5-15 minute.2, adopt model to set roll gap and can also eliminate the roll gap variation that mechanical clearance causes, make fixed value of roller slit more accurate, depress top board crack continuously, dimensional accuracy≤0.1mm.3, adopt model to set the roll gap method, workable and simple, need not skilled operative employee and just can finish and change the groove operation, solved the production efficiency that influences because of personnel are in short supply.4, adopt model can the guide and guard of vertical milling train inlet carry out the adjustment of opening degree and centering equally, guide and guard are changed every and are reduced 2-5 minute.

The utility model is simple in structure, can adjust roll gap quickly and accurately, increases work efficiency greatly, reduces labor strength.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a perspective view of the present utility model.

The specific embodiment

A kind of mill roll-gap is established groove fast and is used model more, as shown in Figure 1, comprise plate body 1, plate body 1 is cuboid, the width of plate body 1 is identical with the gap values between rollers of vertical mill, the height of plate body 1 is identical with the gap values between rollers of flat milling train, affixed handle 2 on the side end face of plate body 1, and handle 2 is arranged along the length direction of plate body 1.The length of handle 2 is 100mm-300mm, and plate body 1 length is 150mm.When model handle 2 length remain between 200 mm-300 mm, both can adjust the 8# mill roll-gap, can adjust the 7# mill roll-gap again, can also insert the guide and guard of 8# inlet, the 8# guide and guard be carried out the adjustment of opening degree adjustment and guide and guard centering.Safety coefficient when decreased food can guarantee that operating personnel adjust, and the length in inserting guide and guard is suitable, plays accurately suitable purpose.

During use, if 7# milling train data are 36*87, and 8# milling train data are 48*48(mm), then model plate body width should be 48 mm, and the plate body height is 36 mm.

Model plate body 1 material is selected high manganese wear-resistant steel (High Manganese Stell Scrap) for use, and high manganese wear-resistant steel plate is the optimal selection of lost materials such as opposing thump, people's pressure material.The characteristics of potassium steel maximum have two: the one, and external shock is big more, and himself surface layer abrasion-proof is high more; The 2nd, along with the wearing and tearing gradually of cementation zone, new work hardening layer can successively form.High manganese wear-resistant steel plate has the excellent abrasion resistance energy to thump wearing and tearing and the wearing and tearing of people's stress, fragmentation can not appear in use, and having easily machining property such as the cutting of being convenient to, welding, bending, the rich chromium cast iron that tradition is used only has wearability preferably to moving wearing and tearing.High manganese wear-resistant steel plate can effectively reduce the use cost of equipment consumable accessory and save the overhaul of the equipments expense, improves roll change efficient.
