Proper designing, selection of raw
material, salt bath heat-treatment, and CNC finished profiles help to
maximize the tonnage per regrind and yields quality end products.
Roll designing is a very critical stage as it affects the cost of the
rolls, life of the rolls, productivity of the mill, and the quality of
the tube / section. DeeTee uses COPRA ( German) software for the roll
designing. The customer has to provide only the basic details of the
mill and the input and output details.
The tube mill rolls are made out of superior quality imported tool
steels. Mostly AISI D2 / 1.2379 / SKD11 AND AISI D3 / 1.2080 / SKD1. The
rod mill rolls are generally subjected to very high working temperatures
and so are made from hot work tool steel grades like AISI H13/ 1.2344 /
SKD 61.
Salt bath heat-treatment is considered to be the best for tool steels.
The high-carbon-high-chromium grades are through hardening steels i.e. ,
when heat-treated they attain the hardness right from the outer surface
till the inner core. Proper heat-treatment gives good toughness, wear
resistance and uniform hardness to the rolls used in rod mill,
tube mill, wire rod mills.
The profile of the rolls are finished on CNC machines resulting in high
surface accuracy and bright shiny finish of the rolls.
DeeTee has a production capacity to make rolls up to 600mm diameter.
