We Specializing In Casting Slag Pot

We Specializing In Casting Slag Pot
On May 23, 2019, we received a project of slag tank from a South American customer. According to the customer's requirements, it is an important equipment for steelmaking in the metallurgical industry. It is a kind of container for holding hot slag generated in the process of steel smelting, and it has bowl-shaped container with lifting lugs on both sides.
 At that time, the South American customer required that the slag tank could hold lead liquid at 900℃ and was made of pearlitic ductile iron, so we recommended qt500-7 ductile iron for him. Qt500-7 is of medium strength and toughness, and has certain resistance to rapid temperature change and corrosion resistance, and adopts sand casting process. Sand casting is a process with a long history and wide application.

Chemical Component of  QT500-7:

Composition(%)
C
Si
Mn

QT500-7
3.40-3.90
2.00-2.90
≤0.60
≤0.05
≤0.03
≤0.10
≤0.10

Mechanical Capacity of  QT500-7:

Tensile Strength MPa
≥500
Yield Strength MPa
≥320
Elongation %
≥7
Hardness HB
170～230HB
Basal Body
Ferrite + pearlite

We sent our Suggestions to the customer. Through communication, the customer asked us to improve the performance of the product, so we finally chose the material qt600-3 and did the annealing treatment. The material is pearlitic ductile iron.

Chemical Component of  QT600-3:

Composition(%)

QT600-3
3.6~3.8
2.4~2.8
0.3~0.5
0.03~0.035

0.045~0.05

Mechanical Capacity of  QT600-3:

Tensile Strength MPa
≥600
Yield Strength MPa
≥370
Elongation %
≥3
Hardness HB
190～270HB
Basal Body
Ferrite + pearlite

Advantage of Bimetal Hammerhead

图片
Advantage of B imetal H ammerhead Hammerhead is a key component on the hammer crusher used in building materials, mining, chemical industry, etc. It is also a wearing part. The traditional hammerhead is mostly cast with high-manganese steel , and the high-manganese steel is used to improve the wear resistance under the impact load, but its wear resistance is far from being suitable for the modern production demand of high efficiency and low consumption. Due to the short life of the hammer and frequent replacement, the equipment operation rate is reduced. Therefore, it is necessary to seek a new material and new technology to improve the function and service life of the hammer. When the hammer head does not change its surface shape at the beginning of the work, the hammer head is mainly subjected to impact wear, and the material impacts the metal surface with a positive force to cause plastic deformation and impact craters. When the working surface of the hammer head is ground...

Wuxi Eternal Bliss Alloy Casting & Forging Co.,LTD Fun B arbecue On April 13, 2019, we organized a deliberate barbecue at Gonghu Bay Park. We rode together to our destination, and as soon as we got out of the car, the warm spring wind blew in front of us with the smell of barbecue. The company's colleagues assembled and started renting barbecues, tables and the like. After the rent began to wash the food, full of bags of food, a variety of fruit, chicken, beef, chicken claws, ham. There must be a lot of brain and energy wasted this time by colleagues who are in charge of buying food materials. It's very hard. Barbecue also requires experience and method. It is impossible to bake delicious food with bamboo sticks in a hasty way. From time to time, pay attention to the fire and oil to prevent the food from scorching. So thank you very much for our colleagues at the barbecue. The smell of barbecue slowly came out, and everyone couldn't wait to take ...
