The reasons and solutions that affect the quality of cast iron platforms

Cast iron platform casting is a metal hot working process that humans have mastered relatively early,with a history of about 6000 years.In modern production,cast iron platform/cast iron flat casting still plays an important role,and the development of the casting industry plays an irreplaceable role in promoting economic development and related industry progress.

As a boss,behind countless halos,successes,and wealth,you also have to face countless moments of struggle and helplessness.If the original intention of entrepreneurs to"change the world"is beautiful and grand,returning to daily operations and exploration,every day is a challenge.

People usually cannot accept your failure.The more brilliant you have been,the more questioning you will bear when you encounter periodic failures.

Although these are difficult for you to accept,you still accept them.Some people move forward because of the light of their dreams,but others have to move forward because of the vast abyss behind them.People who originally wanted to keep their heads up and chest up may sometimes be covered in mud,but even if they can persevere,the mud will eventually dry out and fall off.

Any defect in the use of cast iron platforms will have a significant impact on work,whether it is in terms of service life and accuracy,or on workpiece measurement.Among them,our common problems include cold lines,cracks,cavitation,pores,and peeling.Baichang editor provides a detailed introduction to their causes and solutions:

The question being discussed is-which of the cracks and pores will more affect the cast iron platform?

Firstly,let's explain the reasons and solutions for their occurrence separately,and make a simple comparison before we can see which one will have a greater impact

Problem 1:Cracks

Cause of occurrence:Shrinkage stress and cracking caused by force during ejection or trimming.

Solution:

1.Can increase the rounded corners;

2.Check for any hot spots appearing;

3.The time for boosting slightly changes;

4.Increase or shorten the time for mold closing;

5.Increase the draft angle;

6.Increase top out sales;

7.Check if the mold is misaligned or deformed;

8.Check the alloy part;

Question 2:Pores

Cause of occurrence:

1.Air mixed in the furnace;

2.Gas sources:during melting,in the material tube,in the mold,release agent;

Solution:

1.Appropriate slow speed;

2.Check whether the turning of the flow channel is smooth and whether the cross-sectional area is gradually decreasing;

3.Check if the area of the escape airway is large enough,if it is blocked,and if it is located in the rear filling area;

4.Check if the release agent is sprayed too much and if the mold temperature is too low;

5.Use vacuum.

Based on the above comprehensive analysis,both types of defects will have an impact on the cast iron platform.Therefore,in manufacturing and production,we should pay attention to avoiding the occurrence of each type of problem,so as to produce products that provide customers with a reassuring,worry free,and happy purchasing experience.
