Abstract
A casting-rolling technology for manufacturing the annular steel member includes such steps as smelting raw steel, adding C, Mn and Si to molten steel, heating, casting to obtain semi-finished member, high-pressure rolling, and cutting for shaping. Its advantages are simple technology and high utilization rate of raw material.
Description
Technical field
The present invention relates to a kind of technological method for processing, refer in particular to the processing technology of steel construction piece, be specially casting and rolling machining process for circular steel structure.
Background technology
At present, circular steel structure, as flange, race ring etc., its machining process generally comprises molten steel process, half-finished manufacturing process to be processed, finished product forming process; In half-finished manufacturing process to be processed, all be directly molten steel to be made into continuous casting billet or steel plate, and then utilize continuous casting billet or steel plate processing and fabricating to form; The finished product forming process is divided into the steel plate processing method and forges processing method, also useful centrifugal process (promptly utilizing centrifugal casting machine) processing, but the ubiquitous problem of these processing technologys is an expense material, consuming time, adopts the circular steel structural member of centrifugal process processing, also has the not good enough problem of steel density.
Summary of the invention
The present invention provides a kind of casting and rolling machining process for circular steel structure in order to solve existing above-mentioned defective in the existing circular steel structure processing technology.
Technical scheme of the present invention realizes in the following way: a kind of casting and rolling machining process for circular steel structure comprises molten steel process, half-finished manufacturing process to be processed, finished product forming process; Molten steel process is specially: required raw steel is fused into molten steel with converter, behind assay, elements such as the carbon that lacked in the molten steel, manganese, silicon are supplied, continue then to heat up, make temperature reach 1400 ℃-1600 ℃, become semi-finished product to be processed temperature required to satisfy molten steel casting; Half-finished manufacturing process to be processed is: molten steel is injected mould be cast into semi-finished product to be processed; The finished product forming process is specially: half-finished temperature to be processed is naturally cooled in 600 ℃-1000 ℃ the temperature range, again with semi-finished product to be processed Ring Rolling Machine spreading, after being cooled to room temperature Deng the semi-finished product of processing, utilize the semi-finished product cutting forming after existing metal cutting processing technology will be processed, promptly be made into finished product.
Technology of the present invention is owing to directly utilize to be processed half-finished surplus temperature of molten steel casting moulding, with Ring Rolling Machine semi-finished product to be processed are carried out spreading, omitted forging in the traditional handicraft, towards processes such as cores, on the basis that guarantees end product quality, saved the used time of technological process, and reduced towards the spent raw material of core process, so compare with prior art, save the working time, saved raw material, improved working (machining) efficiency.
