The largest giant radial tire in China was successfully rolled off the Triangle Group
At midnight on September 5, 2010, the largest giant radial tire in China was successfully rolled off at the second production base of Weihai Group in the Delta Group, marking the birth of a new record for domestic giant radial tires. The senior management of the Triangle Group, engineering technicians, production staff and several media reporters witnessed this process on the spot. The product has a specification of 40.00R57, a single tire weight of 3.5 tons and an outer diameter of 3.6 meters. It is mainly equipped with large haul trucks and is an important production material in the fields of mines, energy, and engineering. It has long been dependent on imports in China. Delta Group independently developed the first giant radial tire production line in China and gave full play to the talent advantages of the national-level technology development center. In less than two years, it completed all of the initial design, equipment manufacturing, engineering construction, product development and formal production. jobs. With the birth of the 40.00R57 giant engineering radial tire, Delta has now been able to produce giant radial tire products ranging in size from 49 to 57 inches, making it the most complete and largest domestic radial tire product line. In recent years, the giant radial tire produced by the Triangle Group has successfully provided support for a number of world-renowned construction machinery manufacturers including Caterpillar, Terex, Volvo, Case New Holland, and Liebherr. In the international market won great reputation. In 2008, Delta Group's giant radial tire production technology and equipment won the first prize of the National Science and Technology Progress Award. It is the highest award ever obtained since the tire industry was founded. At present, the Triangle Group is accelerating the construction of the giant project radial tire phase III project. It will eventually form a production capacity of 10,000 radial tires for all series of radial tires from 49 to 63 inches.

Casting Parts:
The casting is a metal human control of hot working
process relatively early, has a history of about 6000 years.In early 1700 BC to
1000 China has entered into casting heyday era,the technology has reached a
very high level.
the material to be casting is usually solid
but heated to a liquid metal (copper, iron, aluminum, lead, tin, etc.), and
mold materials can be sand, metal and even ceramics. In response to different
requirements, the use of the method will be different.

Category:
Casting blank is almost forming, which
achieves the goal of free machining or less processing, reduces cost and
reduces production time to a certain extent. Casting is one of the basic
processes in modern equipment manufacturing industry.
(1) Sand casting:
Using sand as the mold material, also known
as sand casting, foundry, including wet sand, dry sand and chemical hardening
sand 3, but not all are available in sand casting. Advantage is low cost,
because of the use of the mold sand can be reused; drawback is the mold
manufacture time-consuming, repeated use casting model is not possible. To
damage can be achieved after the finished product.
(2) Special Casting Process:
According to the special casting molding
materials can be divided into natural mineral sand as the main materials (such
as casting, mud casting, shell casting, vacuum casting, mold casting, ceramic
mold casting, special casting and metal) as the main cast materials (such as
metal casting, pressure die casting, continuous casting, low pressure casting,
centrifugal casting, etc.
2.1 Metal mold casting method: using high
melting point is the raw material made of metal mold. The subdivision for
gravity casting, low pressure casting and pressure casting method. By casting
the melting point can be cast metal has also been limited.
2.2 Lost wax casting method: this method
can for membrane casting and solid casting. First the object copy the required
casting wax, and then dipped into ceramic containing (or silica sol) in the
pool and stay dry, the wax replica covered with a layer of ceramic membrane,
repeating the steps until the outer membrane is sufficient to support the
casting process (about 1/4 inch 1/8 inch), wax melting in the mold, and out of
the mould. Then many times to enhance the mold temperature, the hardness can be
used to rear casting.
Based on different casting raw material,we`ve
Steel Die Casting,copper alloy die casting and aluminium alloy die casting.
Processing:
(1)The mold preparation (liquid metal become
a solid container for casting ) according to the material used can be divided
into sand, metal, ceramic, clay, graphite, according to the frequency of use
can be divided into single type, semi permanent and permanent mold preparation,
quality is the main factor affecting the quality of castings;
(2) The melting and casting;:casting metal
(alloy) mainly include all kinds of cast iron, cast steel and casting of
nonferrous metal and alloy castings;
(3) The processing and inspection: casting
processing including removal of the core and the casting surface removal of
foreign body, riser, shovel thorn and sanding fash protrusions and heat
treatment, plastic. Anti rust and rough machining.

It is reported that the Delta Group has received the first purchase demand for the product from Hebei Sijiaying Iron Mine, a well-known mining enterprise in China. The large-scale 220-ton haul truck that has recently invested heavily in the mine will be equipped for the first time. Giant engineering radial tires, which marks a new beginning of China's tire industry.
