Description
Technical field
The utility model belongs to technical field of metallurgical machinery, particularly a kind of wire rod bar blooming mill device.
Technical background
The line bar is one of staple product of steel and iron industry, and it is widely used in every infrastructure construction, architectural engineering construction and Steel Wire Products Industry.China began to produce high-speed rod in 1987, and at present, China has become and has the country that high-speed wire production line is maximum, output is maximum in the world.
Before conticaster came out, wire production was to adopt teeming, steel ingot heating back cogging to obtain producing wire rod behind the qualified square billet.Because operation labour intensity such as die casting and cogging are big, environmental pollution is big, energy consumption is high, along with after conticaster successfully uses, each high-speed rod factory eliminates die casting one after another and makes continuous casting into.
Because old breaking down blooming mill version backwardnesss, equipment operation energy consumption height, automatic controlling level is low, equipment quality is heavy, roll is not set separates by device (anti-roll card hydraulic cylinder), do not have roll pass centralising device (roll axial moving device), roll gap adjusting employing adjusting manually etc., therefore old breaking down blooming mill maintenance cost height, labor strength are big, therefore the poor product quality that rolls out is eliminated gradually.
Along with the maturation day by day that conticaster uses, the advanced conticaster of the common all employings of high-speed wire production line is both at home and abroad produced qualified continuous casting billet at present, and continuous casting billet is finished product by modern mill milling, thereby has improved output greatly after heating.But because the product forging ratio that continuous cast billet rolls out is limited, thereby the product specification that causes each manufacturer to produce is limited, product quality is lower, and what produce usually is the low side universal product.
At present, tandem mill (breaking down, in roll, finish rolling) the supplied materials specification all there are certain requirement and restriction, therefore the product specification of producing for the continuous casting billet of a small amount of specification, kind and intensity are limited, and it is also relatively more difficult that conticaster changes casting blank specification, therefore, each high-speed rod manufacturer is in order to reduce cost, improve the quality of products, promote product specification, optimize and widen product structure, improve recovery rate, seek better production process equipment production such as senior cold-forging steel one after another, bearing steel, the steel cord, Prestressed Steel Wire and Strand, products such as senior spring steel.
The present invention can be rolled into continuous casting blooms (more than the 300mm) needed little square billet, has improved forging ratio, just in time can satisfy the said goods requirement, thereby existing milling train is not subjected to the restriction of upstream continuous casting billet specification.
Summary of the invention
The purpose of this utility model provides a kind of advanced person's wire rod bar blooming mill device.This device drives upper working rolls and lower working rolls assembling rotation by main drive, and roller gap drives the top working roll fit on by electric screw down gear and adjusts down, by two roller reversible milling trains continuous casting blooms is rolled into needed little square billet.Wire rod bar blooming mill mainly is installed in high-speed rod and produces in the unit, can be to being rolled into needed little square billet (as: 150mm, 160mm etc.) through the bloom after the heating furnace heating, and finished size is decided according to the roll pass size.
The utility model is different with trimmed size according to the supplied materials specification, same frame can adopt multiple roller diameter (Φ 750mm-Φ 1250mm) and barrel length (1500mm-2300mm), the roll that particularly can adapt to plurality of specifications in same memorial archway window size, thus guarantee the service life that roll is longer and guarantee that the trimmed size scope is more extensive.
The purpose of this utility model is achieved in that by motor (ac variable-frequency electric motor or dc motor), herringbone gear and drives upper working rolls and lower working rolls assembling rotation; Roller gap drives the top working roll fit on by electric screw down gear and adjusts down; Roll pass centering drives the wedge adjustment by the bottom working roll axial adjusting device; The working roll locking device is used to pin upper working rolls and lower working rolls assembling and prevents roll axial float when rolling; The top working roll bascule is used to eliminate and anti-ly rolls quality that gap between card hydraulic cylinder and memorial archway window and the top working roll bearing block and balance top working roll assemble so that the accurate Calculation roll-force; The anti-card hydraulic cylinder that rolls is used for steel rolling and misses and open roll gap when setting rolling steel-fastening fast; Changing rig is made up of working roll push-pull device at fixed and Traverse Displacement Unit, and the working roll push-pull device at fixed can directly be pulled out old roller in milling train, and new roller is directly pushed milling train, and final drive shaft supports by connecing shaft tray during roll change.
The utility model version advanced person, the equipment operation energy consumption is low, automatic controlling level is high, the roll gap automatic setting system, be provided with roll and separate by device and roll pass centralising device, adopt automatic changing rig (roll change cycle short) etc., therefore the utility model can be widely used in wired bar production factory of institute, is used for improving the quality of products, specification.
The utility model can be rolled into continuous casting blooms needed little square billet after implementing, improve the quality of products, promote product specification, optimize the product recovery rate of widening product structure, improving continuous casting output and whole factory, be not subjected to the restriction of upstream continuous casting billet specification, improve forging ratio.The utility model can be installed in all newly-built high-speed rod units or wire rod is transformed in the unit.
