Specialists of the Belarusian metallurgical plant (BMZ) is engaged in the production of hot rolled rebar periodic profile of the quadripartite at the request of one of the European consumers, reported the press service of the BMZ.
To produce a four-sided rebar at the mill 150 rolling plant of BMZ started in August of this year. Distributors have mastered the production of this profile, in nominal diameters: 6, 8, 10, 12 mm. Shipped during this time, more than 7 thousand tons of new products.
Feature a four-sided valve is in its "secretive" nature.
"Core or so called profile body has a square shape, the outer edge of the threaded circle" — explains the acting chief of the section of mill " 150 " Dmitry Tatarinov.
As explained by experts of the factory technical administration, involved in the technological development of a new product, requirements to quality characteristics of the quadripartite rebar is pretty tough. Confirm this yourself by the rollers. To ensure the required level of mechanical properties, geometric dimensions, linear density, and surface rolling was carried out the so-called method relays on the 5 blanks on the party to probe several modes two-stage cooling of the valve. And only after obtaining a stable quality characteristics according to test results it was recommended that the optimum mode of rolling on the production of the base metal of a particular batch of valves.
