Abstract

The utility model discloses a guide slot for adjusting torsion angles of rolled pieces, which belongs to the field of steel manufacturing machinery and particularly relates to a steel production facility. According to the guide slot, a rolling type guide wheel guide rolling piece is additionally arranged in the middle of the guide slot to ensure that the rolled pieces are located in a horizontal state when the rolled pieces pass through the rolling type guide wheel guide rolling piece; the distance between a guide wheel and a bottom plate of the guide slot is designed to be relatively small and slightly larger than the size of each rolled piece; and during the passing, the torsion of the rolled pieces is limited so that the rolled pieces are engaged into a 13 frame, therefore, the problem of improper angles during engagement is improved, so that the technological rolling condition is improved.

Description

A kind of guide groove that is used to adjust the rolled piece torsion angle

Technical field

The utility model belongs to iron and steel manufacturing machine field, is specifically related to a kind of Iron and Steel Production facility, particularly a kind of guide groove that is used to adjust the rolled piece torsion angle.

Background technology

Iron and steel is the alloy that iron and carbon, silicon, manganese, phosphorus, sulphur and a spot of other elements are formed.Wherein, outside the deironing, the content of carbon plays a key effect to the performance of iron and steel, so be called iron-carbon alloy again.The main production process of modern steel integrated complex is divided into two types: long flow process and short flow process.Long flow process is used the widest at present; Its process characteristic is: the iron ore raw material adopts blast furnace to produce molten iron, after Molten Iron Pretreatment after oversintering, pelletizing are handled; By pneumatic steelmaking, external refining to qualified composition molten steel; Be cast into difform strand by continuous casting, be rolled into all kinds of finished products, the iron and steel enterprise in the whole world about 70% takes this flow process to produce; Short flow process can be divided into two types again according to raw material; One type is iron ore behind direct melting and reducing, adopts electric furnace or pneumatic steelmaking, and its main feature is; The iron ore raw material is handled without sintering, pelletizing; Do not have the blast furnace ironmaking production link, this flow process is used less at present, accounts for below 10% greatly; Another kind of be with steel scrap as raw material, after melt smelting by electric furnace, get into subsequent process; There is not the blast furnace ironmaking production link yet; This technological process accounts for 20%, and in order to enhance productivity, domestic and international many steel plant also take to convert the technology of hot metal charging in electric furnace smelting at present.

In general, the production procedure of iron and steel comprises flow processs such as sintering, ironmaking, steel-making, continuous casting, steel rolling.Sintering is exactly iron mineral powder agglomeration, and for blast furnace provides a kind of method of fine fodder, it is to utilize Iron Ore Powder, flux, fuel and return mine and process a process of block raw materials for metallurgy by a certain percentage.The process of ironmaking is exactly the liquid pig iron that temperature and composition meet the requirements that obtains with the iron ore economical and efficient; Realize this process through blast furnace process; May be summarized to be: under the condition of low-energy-consumption of trying one's best; Through the reverse movement of controlled furnace charge and coal gas stream, processes such as high efficiency completion reduction, slag making, heat transfer and the reaction of slag iron obtain the comparatively desirable liquid metal product of chemical composition and temperature.Blast furnace burden is produced qualified molten iron through various chemical reduction reaction and is sent into steel-making through the torpedo jar then, goes into converter smelting Cheng Gang as steelmaking feed then.Slag enters slag bath through flush slag, separates through pulp water, and slag is drained, water circulation use.The byproduct that produces in the blast furnace ironmaking process---blast furnace gas is as uses such as low calorific value gas fuel heat supply wind furnace, sintering, boiler, preheating furnace and heating furnaces.Steel-making is meant that impurity such as carbon too much in the raw material (molten iron and steel scrap etc.), sulphur, phosphorus remove and add the process of the alloying component that adapts to.Continuous casting is meant molten steel in pans inject with water-cooled crystallizer continuously, behind the base shell that congeals into, pulls out with stable speed from crystallizer, through the water spray cooling, after treating all to solidify, is cut into the continuous casting billet of designated length again.Steel rolling is meant that the steel ingot that continuous casting comes out rolls into all kinds of steel with the hot rolling mode at different rolling mills with continuous casting billet, forms the process of product.

Each specification rolling is produced in the design, and 11,12,13 sorties all are the rolling layout of horizontal, and rolled piece needs after going out 12 rolling mills through one section long roller-way, and then after 2# prunes, gets into 13 rolling mills.Because 12 rolling grooves be circle in each specifications design process, reverse to cause and be difficult to nip down the sortie milling train because of what produce in the operation of rolling avoiding.And in four cutting processes, 11 set up and count flat rolling; The empty mistake of 12 sorties, going out the supplied materials type from 11 sorties is rectangle, empty 12 and 12 long empty the roller-way between cutting with 2# of crossing; Owing to producing the reason of reversing in the operation of rolling; When 2# cuts the width of rolled piece will and 13 rolls between form a bigger angle, seriously influenced the state of nipping of rolled piece, can cause heap steel accident.

The utility model content

In order to solve because of reversing of producing in the operation of rolling cause nipping the down inappropriate technical problem of the angle of nipping of sortie roll; Reduce heap steel accident; The utility model provides a kind of guide groove that is used to adjust the rolled piece torsion angle; It is made up of guide groove body, guide wheel, turning cylinder and guide wheel bracing frame, and the guide wheel bracing frame is fixed on the guide groove body, and guide wheel connects with the guide wheel bracing frame through turning cylinder.

The utility model is through the spacing of design guide wheel and guide groove base plate; That comes to produce in the limited rolling process reverses, and 12 specifications, four cutting supplied materials material height is 26mm, and wide is 54mm; Therefore; Described guide wheel and guide groove base plate spacing are that 26mm-54mm is advisable, and especially good is, when described guide wheel and guide groove base plate spacing are 40mm.

This utility model is through in the middle of guide groove, increasing a roller guide wheel guiding rolled piece; Make rolled piece through the time rolled piece be in level; Design the spacing between guide wheel and the guide groove base plate less, be a bit larger tham workpiece measurement, so that nip 13; The inappropriate problem of angle when improving it and nipping, thus the rolling mill practice situation improved.

The place opens guide groove at guide groove body upper cover plate, settles guide wheel, guide wheel in design process for can better guide rolled piece; The diameter of guide wheel is 250mm; Make the contact angle of rolled piece and guide wheel reduce, avoid occurring excessive, be obstructed and cause heap steel accident because of contact angle.

After transforming through this utility model, following beneficial effect is arranged: solved because of the rolling unaccommodated problem of angle when reversing nipping of bringing, improved the state of arts of splitting rolling, improved product quality.
