Abstract
The invention discloses a deformed steel production process, which comprises heating and rolling, wherein the heating temperature is 1,000 to 1,400 DEG C, and the rolling compression ratio is 14 to 17. Deformed steel obtained by the process has a smooth and burr-free rolled surface, and is high in quality, and the metallographic structure of a product is consistent with a national standard.
Description
Technical field
The present invention relates to metal working technical area, especially a kind of deformed steel production technology.
Background technology
Development engineering machinery is the important equipment of the development of the national economy, occupies very important status in equipment manufacturing industry.The Construction Machinery Industry in China income from sales of 2007 is 2,223 hundred million yuan, occupies world's construction machinery industry second.From calendar year 2001 by 2007, average annual growth rate is more than 24%.Export amount rises to 8,700,000,000 dollars in 2007 from 1998 2.24 hundred million dollars, increases 37 times between 10 years.At present, the construction machinery industry of China occupies critical positions in the colleague of the whole world, and product has exported to the engineering machinery poweies such as American-European, strides forward to " manufacturing big country " and " manufacturing power ".
China's Machinery Enterprises is compared with large-scale engineering machinery international conglomerate, and competitiveness is also more weak.In the journey of marching toward construction machinery production power, the situation of development will be severeer, facing challenges will be larger." world Liu work; be derived from China ", in the high speed process of the diversification of the personalization of economy and the globalization in market, the fieriness of competition and demand and judicial convenience, relevant benefit main body, development in science and technology, be that the foreign capitals of representative are when brining the engineering machinery industry of China into its global industrial chain in trans-corporation, willow workman also in action, they are while striving for survival on the basis of quality, try every possible means shorten key components and parts procurement cycle, shorten new product development cycle, cultivate a collection of excellent auxiliary products producer.Background by this, Liuzhou Jindun Machine Co., Ltd. set up in 2005, and a step step upper in nearly 3 years, within 2007, sales achievement is then more than 8,000 ten thousand yuan.Now, company sees the great potential of the extraordinary deformed steel demand of engineering machinery, and Liu work at present only from other provinces a channel stock up, procurement cycle is long, has much room for improvement to the response speed in market.Company relies on the responsive sense of smell to market, involve in rapidly the production of the extraordinary deformed steel of engineering machinery from raw material to finished product,, response timely supporting producer supporting with the region meeting Liu work, becoming one the most at last can the supporting extraordinary deformed steel manufacturing enterprise of engineering machinery in the whole nation.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of deformed steel production technology, easy and simple to handle, product quality is high.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of deformed steel production technology, comprises heating, roll, this heating-up temperature is 1000 ~ 1400 DEG C; The compression ratio of this roll is 14 ~ 17.
Further, this heating-up temperature is 1200 DEG C; The compression ratio of this roll is 15.
Compared with prior art, the present invention has the following advantages: adopt the deformed steel that this technique obtains, and have smooth, carrot-free rolling surface, product metallographic structure meets national standard, and quality is high.
Detailed description of the invention
Describe the present invention below in conjunction with embodiment, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
embodiment 1
A kind of deformed steel production technology, comprise heating, roll, this heating-up temperature is 1000 DEG C; The compression ratio of this roll is 17.
embodiment 2
A kind of deformed steel production technology, comprise heating, roll, this heating-up temperature is 1400 DEG C; The compression ratio of this roll is 14.
embodiment 3
A kind of deformed steel production technology, comprise heating, roll, this heating-up temperature is 1200 DEG C; The compression ratio of this roll is 15.
According to product size and stock dimensioned parameter:
By this explained hereafter deformed steel product out, because shape is originally close to actual installation shape of product, can saving steel use amount in a large number, when carrying out fine finishining, the process-cycle processes shortening 5-10 times than raw material.
Temperature range in this technique, if low, shaping difficulty is large, and the damage of breaker roll is worn and torn just large in other words, increases unnecessary load to motor; Temperature exceedes technological requirement and too high, then have the blank superheating phenomenon even burning rolled out.Burning then will be scrapped, and brings unnecessary loss.And its mechanical performance of overheated blank also will be had a greatly reduced quality.
And the compression ratio of roll, in theory, hot rolling compression ratio >=10 of section bar can meet the mechanical performance index such as tensile strength and percentage elongation of deformed steel.In this technique, Roller Design provides the rolling of 7-15 passage, and the compression ratio of shaped steel is about 15, can reach its mechanical performance index completely.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
