Abstract
The utility model relates to an accessory for a rolling machine, particularly to a mechanical clamping type wear-proof cast iron guide board, which is composed of a service wearing part and a basal body non-wearing part, wherein the service wearing part is made of abrasion-resistant cast iron, the basal body non-wearing part is made of low alloy cast steel, and the service wearing part and the basal body non-wearing part are connected in the mechanical clamping mode. The serious wearing point of a guide plate is provided with a slot which is matched with an abrasion-resistant cast iron inserting block. Both ends of the slot have the inclination of 6 DEG to 8 DEG. Four screws are arranged in the slot of the guide plate for adjusting the plane of the abrasion-resistant cast iron inserting block. The abrasion-resistant cast iron inserting block is arranged in the slot and a pressing block is fastened by a bolt. Both sides of the abrasion-resistant cast iron inserting block are symmetrical; when one side is abraded, the other side is changed to be continuously used.
Description
Affiliated technical field
The utility model relates to a kind of rolling mill accessory, and especially a kind of serious wear position is the replaceable mechanical clamping type guide plate of inserting.
Background technology
The finishing mill entrance guide plate is the crucial quick-wear part of rolling mill, in the rolled steel process, have the blank of importing and escort effect, its working face contact temperature is 1100 ℃～1200 ℃, bear impact, friction and the extruding of red-hot steel billet simultaneously, and the Quench of cooling water, working condition is more abominable, and the working position wearing and tearing are very serious.So it is guide plate is changed more frequent, also bigger to producing influence.This shows, need comprehensive mechanical performance under the normal temperature, also need the comprehensive mechanical performance under the high temperature simultaneously for guide plate.Therefore, select scientific and rational material and manufacturing process for use, produce higher guide plate in service life, all significant to enhancing productivity, reducing production costs.
At present, the guide plate that domestic many steel rolling mills use grey cast-iron, white cast-iron, spheroidal graphite cast-iron, low-alloy steel, Gao Ge, nickel alloy antifriction cast iron to produce more, substantially all be overall structure or insert type, again in the operation of rolling, the abrading section of guide plate only is its front end, and the most surfaces wearing and tearing are little, only play the guiding role.Integral guide plate has following shortcoming, and integral guide plate needs only concentrated wear, and whole pair of guide plate all will be scrapped; Consume a large amount of valuable alloy materials, thereby increased the cost of steel rolling.Every on arrowband finishing mill guide plate is heavy 16 kilograms, and the more serious less part of having only of wearing and tearing.
Summary of the invention
It is common steel alloy that the purpose of this utility model provides a kind of guide plate body, and the serious wear position is that antifriction cast iron is inserted, and by adopting the mode of mechanical clamping, they is combined.It can give full play to the potentiality of antifriction cast iron, reduces the usage quantity of valuable alloy, can use repeatedly again, reduces production costs widely, and is both economical, scientific and reasonable again, to overcome the deficiencies in the prior art.
The technical scheme in the invention for solving the technical problem is that the utility model is made up of two parts, i.e. service wear part and the non-wearing part of matrix.Service wear partly is an antifriction cast iron, and the non-wearing part of matrix is a low-alloy cast steel.These two parts connect with mechanical clamping mode.Guide plate serious wear place processes a groove, inserts with antifriction cast iron and matches.There is 6 °～8 ° gradient at the two ends of groove.Four screws are arranged, to adjust the plane that antifriction cast iron is inserted in the guide plate groove.Antifriction cast iron inserted put into groove, briquetting is got final product with bolted.The antifriction cast iron two sides symmetry of inserting, behind a surface wear wherein, replaceable another side can continue to use.Like this, an antifriction cast iron is inserted and just can be used twice.After all wearing and tearing in the two sides, can be by continuing use after the REPAIR WELDING.
The beneficial effects of the utility model are, simple in structure, cost is low, and the weight of valuable alloy material only is 1/8th of guide plate, and can use on the two sides.Therefore, the cost of clip type antifriction cast iron guide plate greatly reduces.Antifriction cast iron is inserted by REPAIR WELDING, and cost is further reduced.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done detailed explanation.
Accompanying drawing 1 is the wear-resistant figure of inserting.
Accompanying drawing 2 is wear-resistant locations drawing of inserting in guide plate.
Accompanying drawing 3 is structure charts of the high chrome molybdenum antifriction cast iron of clip type guide plate.
(1) guide plate among Fig. 3 (the non-wearing part of matrix), (2) nut, (3) fastening bolt, (4) briquetting, (5) nut, (6) are adjusted bolt, (7) are wear-resistant (service wear part) (8) adjusting pad of inserting.
The specific embodiment
Process a groove in the more serious part of guide plate (1) wearing and tearing, wear-resistant inserting (7) is placed in the groove, and groove matches with wear-resistant inserting (7).There is 6 °～8 ° gradient at the two ends of groove (guide plate length direction).Wear-resistant inserting (7) also has 6 °～8 ° gradient with the corresponding position of groove.There are four screws at the back side in the guide plate groove, to adjust wear-resistant plane of inserting.Wear-resistant inserting (7) put into groove, briquetting (4) is used fastening the getting final product of bolt (3).Briquetting (4) also has 6 °～8 ° gradient with groove and wear-resistant inserting (7) corresponding position.Loosening in order to prevent bolt (3), with nut (2) locking.If wear-resistant insert and groove between the gap bigger, the suitable adjusting pad (8) that can add thickness is adjusted.The wear-resistant two sides symmetry of inserting, behind a surface wear wherein, replaceable another side can continue to use.Like this, one wear-resistant just can be used twice.After all wearing and tearing in the two sides, can be by continuing use after the REPAIR WELDING.
Claims (4)
1, a kind of clip type antifriction cast iron guide plate is characterized in that: by guide plate, nut, fastening bolt, briquetting, nut, adjustment bolt, wear-resistantly insert, adjusting pad etc. forms.
2, clip type antifriction cast iron guide plate according to claim 1 is characterized in that: process a groove in the more serious part of guide plate wearing and tearing, antifriction cast iron is inserted and is placed in the groove.
3, clip type antifriction cast iron guide plate according to claim 1 is characterized in that: the two ends of groove, promptly the guide plate length direction has 6 °～8 ° gradient, wear-resistantly inserts, also there is 6 °～8 ° gradient the corresponding position of briquetting and groove.
4, clip type antifriction cast iron guide plate according to claim 1, it is characterized in that: the guide plate matrix is common steel alloy, inserts to be antifriction cast iron.
