Embodiment Construction

[0016] At present, industries such as building structure and machinery manufacturing have very strict requirements on the specifications and models of multi-purpose special-shaped channel steel. For this reason, the following production methods of multi-purpose special-shaped channel steel are adopted:

[0017] The first step: tempering

[0018] Step 2: Start

[0019] The third step: pickling, phosphating, saponification

[0020] Step 4: Cold dial

[0021] Step 5: Straightening

[0022] The technical solutions of the present invention are described in detail below through embodiments:

[0023] Choose the blank to be processed as 35mm×55mm×11mm cold-formed steel, and then perform the following cold drawing process one by one.

[0024] 1. In order to ensure the effect of cold drawing, it is necessary to heat-treat the blank in a continuous heating furnace, that is, tempering. When tempering, ensure that the furnace temperature is 750 degrees Celsius and the speed is 500 rpm.

[0025] 2. Afte...

Abstract

The invention discloses a method for producing multi-purpose deformed channel steel, which comprises the following steps of: 1, tempering; 2, heading; 3, pickling, phosphating and saponifying; 4, cold drawing and 5, straightening, wherein in the tempering step, a primary blank is subjected to heat treatment in a continuous heating furnace at the temperature of 750DEG C and a rotating speed of 500 revolutions/hour. The method has the advantages that: the process flow of tempering, heading, pickling, saponifying and cold drawing is strictly limited, the furnace temperature, heading length, the preparation of pickling and saponifying solution, and pickling and saponifying time, which are required to be noticed, are confined, and the multi-purpose deformed channel steel with high strength, uniform specification and high toughness is produced.

Description

Technical field [0001] The invention relates to a production method of channel steel, in particular to a production method of multi-purpose special-shaped channel steel suitable for building structures, machinery manufacturing and other industrial structures. Background technique [0002] The product has always been dependent on imports, and the price is extremely high. There was a domestic enterprise producing it, but because the production process used was hot rolling, the surface of the product was rough, especially the size of the foot hooks did not meet the user requirements, but our company adopted the cold drawing process, the surface of the product is high, and the foot hooks The size meets the standard and is welcomed by users. Summary of the invention [0003] Aiming at the shortcomings of the prior art, the present invention provides a new type of production method of multi-purpose special-shaped channel steel. [0004] In order to achieve the above objectives, the meas...
