Abstract
A disk-type shear knife is made up of No.45 steel with carbon content of 0.45-0.50%. Its heat treating technology features quenching at 850-870 deg.C for 2-3 min/mm, cooling agent, circulating water and tempering at 300-320 deg.C for 8-15 min/mm.
Description
The present invention relates to the material selection and the manufacturing process thereof of slitting knife sheet.
Be used for slitter and open the disc shear blade thereby of band, generally adopt alloy tool steel manufacturing, material commonly used is the 9SiCr steel.Product requirement hardness H
RC48-52.Make disc shear blade thereby with alloy tool, thermal treatment process is very complicated, will pass through earlier to comprise: giving of operations such as Spheroidizing Annealing, normalizing, low-temperature annealing, modifier treatment is equipped with thermal treatment, and then quenches, and heat-eliminating medium is an oil.The disc shear blade thereby made from the 9SiCr steel is though hardness can reach H
RCMore than 50, but complex process, the manufacturing cost height.
Purpose of the present invention is intended to overcome the shortcoming of prior art, and a kind of disc shear blade thereby and thermal treatment process thereof are provided, and makes product satisfy under the prerequisite in work-ing life, and simplified manufacturing technique reduces production costs.
The objective of the invention is to be achieved through the following technical solutions.A kind of disc shear blade thereby and thermal treatment process thereof, shear blade adopt carbon content to be controlled at No. 45 structural carbon steels of 0.45-0.50%, and thermal treatment process is the Wen Huoshi tempering, and quenching temperature: 850-870 ℃, soaking time 2-3 branch/millimeter; Refrigerant: recirculated water; Tempering temperature 300-320 ℃, soaking time 8-15 branch/millimeter.
The present invention compared with the prior art because the material of disk scissors is selected common 45 steel for use, price wants cheap many than alloy tool steel, and the thermal treatment process that is adopted is simple, therefore, production cost of products is low.Owing to the upper limit that the carbon content of material is controlled at standard, rational heat treatment technology makes the final quality of product can reach design objective in addition, satisfies the requirement in work-ing life.
Through the product Hardness Surveillance, the present invention and prior art (9SiCr steel shear blade) correlation data such as following table:
| The check position | H RCOn average | ||||||
| 1 | ?2 | ?3 | ?4 | ?5 | ?6 | ||
| Product 9SiCr steel shear blade of the present invention | 48 55 | ?53 ?52 | ?50 ?53 | ?49 ?56 | ?52 ?54 | ?55 ?54 | ????52 ????54 |
Use contrast through the user, 9SiCr steel shear blade, twice sharpening timed interval can be processed 700-800 ton steel band, and shear blade of the present invention can be processed the 1000-2000 ton.The user proves that the every cover of shear blade of the present invention can produce ten thousand tons of steel bands of 3-5.
Be embodiments of the invention below:
Example 1,352 millimeters of diameters, 20 millimeters disc shear blade therebies of thickness, material 45 steel, Chemical Composition (%): carbon 0.45, silicon 0.35, manganese 0.70.Steel billet forms through forging, roughing, modifier treatment, precision work, hardening and tempering process: quenching temperature: 850 ℃, and soaking time 40 minutes; Water-cooled (recirculated water); 320 ℃ of tempering temperatures, soaking time 225 minutes.
Example 2,320 millimeters of diameters, 15 millimeters disc shear blade therebies of thickness, material 45 steel, Chemical Composition (%): carbon 0.50, silicon 0.37, manganese 0.80.Steel billet forms through forging, roughing, modifier treatment, precision work, hardening and tempering process: quenching temperature: 870 ℃, and soaking time 45 minutes; Water-cooled (recirculated water); 320 ℃ of tempering temperatures, soaking time 225 minutes.
Example 3,180 millimeters of diameters, 10 millimeters disc shear blade therebies of thickness, material 45 steel, Chemical Composition (%): carbon 0.48, silicon 0.30, manganese 0.60.Steel billet forms through forging, roughing, modifier treatment, precision work, hardening and tempering process: quenching temperature: 860 ℃, and soaking time 25 minutes; Water-cooled (recirculated water); 310 ℃ of tempering temperatures, soaking time 100 minutes.
