Laba porridge is drunk during Laba Festival, and after Laba is the year-Yikuang Technology
The annual traditional Laba Festival is coming. According to Buddhist scriptures, Sakyamuni, the founder of Buddhism, meditated and sat under the bodhi tree. The day of enlightenment and buddhism was also on the eighth day of December. Therefore, Laba is also a Buddhist festival, also known as the "Buddha to Taoism Festival". On this day, Chinese Buddhists use whole grains supplemented by kidney beans, ginkgo, red beans, longan meat, lotus seeds, red dates, peanuts and other fruits to cook porridge for the Buddha, called Laba porridge, and gradually evolved into a folk custom.

How to match the geological drill pipe with the drilling rig?
Answer: Φ34mm-Φ50mm small diameter geological drill pipes can be used together with pneumatic column drilling rigs (ZQJC160 to 1000) with torque below 1000N/m/full hydraulic tunnel drilling rigs for coal mines (ZDY400, 540, 650, 1200). Large diameter geological drill pipes above Φ63.5mm are generally used together with full hydraulic drilling rigs (ZDY1900, 3200, 4000,) and crawler full hydraulic tunnel drilling rigs (ZDY6000), in addition, the matching of drill pipe and drilling rig should also take into account the drilling diameter and depth of the drilling rig, and the drilling diameter is inversely proportional to the depth.

What is the material of 42CRMO and 42CRMOA and what is the difference?
Answer: There is a symbol after the grade of round steel, which means that the content of phosphorus and sulfur is low. There is no difference between 42CRMO and 42CRMOA in other aspects, and we know that the content of phosphorus and sulfur will seriously affect the performance and strength of steel. The one with A indicates high quality, less impurities and better performance.
