• FeaturesGood surface finish, Minimum variation( cylindricity and ovality) in the roll diameter

Being very small in diameter and longer in length, this is the most difficult item to make amongst all the rolls. DeeTee is the only company in India who is manufacturing the leveler rolls from the route of induction hardening. The minimum diameter leveler roll that DeeTee is manufacturing is of 25mm dia.Thru induction hardening, the skin of the roll gets hardened but the core remains soft. This allows the roll to absorb the bending force and retain its original shape automatically during application.

Sendzimir Mill Cluster Mill Rolls, 20 Hi Mill Rolls comprises of Work Rolls , 1st intermediate rolls, 2nd intermediate rolls, Z hi Mill rolls, and back-up bearings. work rolls are very small in diameter. work rolls are generally made out of D2 1.2379 or HSS material. The 1st and 2nd intermediate rolls are made from 1.2362 H11 D2 material. Since all these grades come under the category of tool steels , they are heat-treated in salt bath furnaces. Salt bath treatment gives excellent uniformity of hardness and is considered to be the best method for tool steel hardening. Sendzimir mills are generally used for rolling of stainless steel and non-ferrous grades worldwide. these mills operate at speeds ranging from 500 MPM to 1000MPM. At such high speeds, it is very necessary that the material of rolls is very clean and free from inclusions and defects and should be of very good quality. DeeTee can make all sizes of sendzimir 20 hi rolls from 20mm to 300mm diameter.

DeeTee offers a complete range of Slitting Line Tooling confirming to international standards - Rotary Metal Slitting knives, Metal Spacers, Rubber bonded spacers, stripper rings, Over arm Separator Discs , shims and other precision tools. Heat treated in salt bath furnaces, DeeTee’s slitting line tooling has the highest degree of hardness uniformity and the ideal metallurgical properties to slit any metal. DeeTee manufactures slitting line tooling in Standard and Extra Precision tolerance grades with lapping. Standard for slitting strips above 1mm thickness and Extra precision grade for foils up to .2mm thickness. DeeTee can manufacture Slitting Line tooling up to 600mm diameter.

DeeTee rolls out world class forged rolls- Sendzimir mill rolls cluster mill rolls, 6Hi, 4Hi and 2Hi mill rolls, skin-pass rolls etc. The rolls are prone to very tough working conditions and have to be perfect in terms of wear resistance, toughness and hardness. Right from the raw-material inspection, to heat treatment , to grinding and final dispatch, all rolls undergo very stringent quality checks. The raw-material is generally imported from renowned sources from worldwide and is checked for – macro structure analysis, micro structure analysis, ultrasonic soundness and heat-treatment response. Proper heat-treatment cycles ensure hardness uniformity and proper depth of hardness.

SHEAR KNIVES & BLADES are manufactured from best quality alloy steel. Information on specific application of blades is to be provided by the customer. Raw material is selected by DeeTee and heat treatment is imparted in accordance with the specifics application to maximize the blade performance. The shear blades are finally ground to close tolerance so that they conform to most rigorous international standards about parallelism and flatness.

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.
