What are the functions and quality requirements of increasing the density of alloy steel castings
May 25, 2018

Alloy steel castings can be effectively divided into metal gravity casting, gypsum gravity casting, sand mold casting, lost foam casting, special casting and so on. In the process of manufacture, it is effective to pour liquid or semi-liquid metal or alloy into the die chamber of the die casting machine to fill the cavity at high pressure and high speed, and to form and crystallize the casting at high pressure to obtain a kind of forming method.

The cast steel square ruler of alloy steel castings is an indispensable tool in the process of producing alloy steel castings. To some extent, it is mainly due to the influence on the quality of the products. Today, the use of alloy steel castings is analyzed and discussed in detail. Let's see how it works.

 

1.Alloy steel castings need to effectively check whether the precision of alloy steel castings is up to standard before use, to check whether the face and workpiece of alloy steel castings are wiped clean, to check whether the measured surfaces are bruised, A factor affecting the measurement, such as a burr.

 

2.Check whether the machine is off, do not measure the running of alloy casting, otherwise it will damage the cast steel square and prone to accidents. The cast steel square ruler cannot measure the overheated or undercooled workpiece, and the cast steel square ruler should not pull back and forth on the measuring surface of the steel castings to be tested, but should measure one place so that the cast steel square ruler is separated from the measuring surface of the steel castings to be tested and another place should be measured.

 

3.When measuring the perpendicularity, the cast steel square ruler is placed on the face of the steel castings to be tested. The angle of the workpiece is identified by the light gap method or the plug rule, and the working face of the cast steel square ruler shall be in complete contact with the cast alloy steel castings when the workpiece's outer angle is checked. Then according to the size of the optical gap to determine whether the workpiece is qualified.

 

4.When measuring the vertical degree, attention should be paid to the position of the cast steel square ruler should not be skewed, and the face of the cast steel square ruler should be perpendicular to the castings of the alloy under test, otherwise the measurement error would be produced, and in order to obtain the accurate measurement results, The cast steel square ruler can be flipped and measured again with other measuring surfaces, thus eliminating the deviation of the cast steel square ruler itself.

What is the effect of increasing the density of alloyed steel castings

1.The higher the density, the less likely will be bubble, crack and other defects, thus reducing the waste rate. 

2.The more dense products are used as precision alloy castings, the more precise the steel structure will be.

 

3.The effect of density on toughness is also very large, and the higher the density, the higher the toughness.http://www.wuxiorient.com/
