Product Details
CADI is to add some carbide forming elements on the basis of the composition of austempered ductile iron (ADI), so as to form certain carbides in the structure of ADI. Its abrasion resistance is higher than that of ordinary ADI, reaching the performance of high alloy abrasion resistant cast iron, and its plastic toughness is better than that of high alloy abrasion resistant cast iron.
CADI grinding balls can be widely used in mining, power cement production and other industries. Its main features are:
(1) High hardness and toughness, with work hardening characteristics, and the depth of hardened layer is about 2mm;
(2) In the application of actual working conditions, the wear is about 1/2 of that of other grinding balls, that is, the service life is increased by more than one time;
(3) The overall uniformity of the grinding ball is good, and the crushing rate and out of roundness rate are extremely low in practical application;
(4) Due to the characteristics of the grinding ball, such as no breakage, no loss of roundness and low specific gravity, the starting and operating power of the ball mill can reduce the power consumption of the whole system by about 10%;
(5) The operating power is reduced, the wear of equipment is also reduced, the service life is extended, and the maintenance cost is reduced.

Use effect of grinding ball after 2 months of operation
The average ball consumption of CADI grinding ball is 327g, and the average ball consumption of other manufacturers' hot balls is 786g/t, and the unit consumption of grinding ball is reduced by 58.4%. CADI grinding ball shows a perfect combination of hardness and toughness. During use, it is hard to work, with low wear rate, low crushing rate and no loss of roundness.
The company focuses on casting manufacturing, with excellent equipment and advanced technology. At present, there is one V-method casting production line, one alkaline phenolic resin sand casting production line, and a set of sodium silicate sand production equipment. Four sets of 20t and one set of 5t medium frequency electric furnaces are used for smelting, supplemented by one set of 30t VOD refining furnace and one set of LF refining furnace, equipped with direct reading spectrometer made in Germany to detect the composition of molten steel, and supporting casting heat treatment equipment to ensure that high-quality products are obtained.
Ron mold coated sand production line
There are 5 iron mold sand coating production lines in total, which adopt domestic professional automatic iron mold sand coating lines and semi-automatic shell molding lines, and can produce 100000 tons of castings annually and use 2 tons, 3 tons and 5 tons of medium frequency induction furnaces for smelting.
Resin sand production line
The workshop of resin bonded sand production line covers an area of 9220 ㎡, with two 15 ton holding furnaces, a 5 ton one driven two medium frequency induction furnace and a 2 ton medium frequency induction furnace. It also has a 15 ton resin bonded sand production line (including sand mixer and gas annealing kiln), producing the largest 15 tons of castings/piece and the smallest several kilograms of castings, with an annual output of 20000 tons of castings. Corresponding cleaning and painting equipment shall be provided. The products are suitable for metallurgy, mining, mineral processing, railway, automobile, ship, power, building materials and other industries.
Vmethod molding production line
It is specialized in introducing V-shaped production line for SAG mill to produce special shell steel lining plate for SAG mill. The shell steel lining plate is perfectly designed and customized with new technology. Through isothermal quenching technology, the hardness, toughness and yield strength of the lining plate are improved. After use, it has the ability of work hardening to increase the surface hardness by 8-10HRC, enhance the material's resistance to deformation and increase the wear resistance, greatly extend the service life, reduce the customer's cost The time for replacing lining plate is reduced, the running rate of SAG mill is increased, and the product output is increased.
Heat Treatment Center
The heat treatment center was founded at the end of 2007, covering an area of 2100M2. It introduced two advanced isothermal rate heat treatment production lines from AFC-HOLCROFT of the United States. Later, on this basis, after the improvement and optimization of the company, it independently developed a 5-ton heat treatment furnace and a continuous production heat treatment furnace, which can achieve an annual output of 40000 tons.
AFC-HOLCROFT introduced the world's most advanced isothermal quenching heat treatment production line - UBQA. The equipment includes converter, preheating furnace front chamber, air exchange chamber, rear chamber, cleaning machine and supporting facilities. It is at the world's advanced level in the field of salt melt quenching furnace, and has the following characteristics
1) Advanced PLC control system and fully automatic management make production more convenient and efficient.
2) The patented cooling system is adopted for the quenching tank, so that the hardening depth of the workpiece can reach more than 152 mm;
3) Multiple cooling methods are used together to ensure that the temperature change of the salt solution when the workpiece enters the quenching tank is controlled within 5 ° C within the specified time, and the body protection ensures that the workpiece will not be oxidized to obtain good surface quality
