Cast iron weights of main features:

1, cast iron weight refers to the weight of heavy application of iron.

2, light industry also needs heavy rail, light weight iron on is mainly used to increase the weight for balance or increase their feeling of heavy rail.

3, applied in light industry, the counterweight is mainly formed by machining material.

4, heavy weight iron generally classified according to method is customarily divided into sand-weight iron and heavy iron.

Cast iron weight parameters:

Specifications: 5T/3T/2T/1T/500KG/200KG/100KG/50KG/20KG/25KG/10KG/5KG

Shape: regular 500KG-standard weight. 500KG-5T conventional square, you can fork out dual-use. Cylindrical, round lines and so on, can also be customized according to the drawing.

Cast iron weights Note: clear the weight of surface corrosion, and wipe with cotton yarn stained with oil, until the surface so far. with a high precision scales, weigh the weight has been addressed, the calculation of reduced quality, remove screws on the weight, wire up and screw on.

Weight of cast iron spray paint rust-proof on both sides without package

For scale, pounds of iron, electronic flat scales, elevators, and other types of industrial scale calibration. To ensure accurate scale body

Used to measure test and experiment!

Specifications vary in size.

Class: M1 material: cast iron

Shape:-locking, rectangular, cylindrical, square

Color: normal is black. (Optional)

Cast iron weight profile: lock, cylindrical, rectangular, scroll, hook type, shape, shape, ring (rings), riding, (bar)

Cast iron weights defined: cast iron weights are used to increase the weight for balance weights, is blasting machine melting into liquid and pour it into the mold that meet certain requirements, solidification, after clearing have predetermined shape, dimensions and characteristics of the casting process. Counterweight was one of the basis of modern machinery manufacturing technology.

Cast iron weight material:

1, according to GB and GB 9439 1348 manufacture.

2, under the provisions of GB 5612, gray cast iron casting on a ф 30 bar tensile strength, which can be divided into HT100, HT150, HT200, HT250, HT300 HT350 six materials.

3, material under the provisions of GB 5612, ductile iron grades divided into Dan Zhu, cast block class.

4, Dan Zhu blocks the mechanical properties are divided into QT400-18, QT400-15, QT450-10, QT500-7, QT600-3, QT700-2, QT800-2, QT900-2 and eight kinds of materials.

5, report of the mechanical properties of cast blocks QT400-18A, QT400-15A, QT500-7A, QT600-3A, QT700-2A five kinds of materials.

Cast iron weight technical requirements:

1, production methods, chemical composition and heat treatment methods of production, chemical composition and the heat treatment process by the supplier's discretion, but must ensure that the provisions of this standard and related documents cast iron grades and corresponding indicators of mechanical properties.

2, such as the organization or the customer on the chemical composition and heat treatment method with special requirements, in the order provided for in the agreement or related documents by both parties.

3, mechanical properties.

4, Dan Zhu test bar (block) the mechanical properties.

5, according to Dan Zhu of this standard test bars into sample to determine the tensile strength of gray cast iron, nodular cast iron mechanical properties tensile strength and elongation of two indicators as a basis for acceptance.

6, nodular weight tiedanzhu block impact test applies only to table 2 grades, and only if the organization or customer requirement to do impact test, the shock value as evidence of the acceptance.

7, counterweight generally classified according to method is customarily divided into sand-weight iron and heavy iron.

8, sand-weight iron include green sand, dry sand, three types of chemical hardening sand.

Cast iron weight dimensions:

Lock a ton weight: length: 600mm width: 600mm height: 495mm

A ton of Tablet weight: length: 1200mm width: 600mm height: 235mm

Grooved plate weight: length: 1100mm width: 540mm height: 350mm

500kg lock-shaped weight: length: 530mm width: 425mm height: 410mm

200kg lock-shaped weight: length: 485mm width: 275mm height: 280mm

100kg lock-shaped weight: length: 380mm width: 210mm height: 235mm

50kg lock-shaped weight: length: 270mm width: 205mm height: 210mm

25kg lock-shaped weight: length: 240mm width: 160mm height: 160mm

20kg lock-shaped weight: length: 210mm width: 150mm height: 150mm

10kg lock-shaped weight: length: 190mm width: 100mm height: 115mm

5kg lock-shaped weight: length: 150mm width: 85mm height: 90mm

Divided into two types:

First: with natural mineral aggregate as the main molding materials, such as investment counterweight, shell weight iron, vacuum counterweight, mud weight iron, real counterweight, ceramic counterweight.

Second: to the metal as the main cast material, such as metal counterweight, flyweight iron counterweight in a row, pressure with heavy iron, low weight iron, with heavy iron process can be divided into three basic parts, namely weight iron metal preparation, mold preparation and casting process.
