Management Proposal :: Management Report Summary

Management Proposal Deep-well drilling has been around for centuries. Over the years, different techniques have been developed in order to improve the efficiency of drilling in a number of different geographical locations. Today’s deep-well drilling industry revolves around the use of bits. In order for this company to be proficient with time and money, it is essential to use bits that are tough enough to withstand impact, while at the same time still possessing a hard surface to protect it against wear. Case hardening will be the method of choice because of it’s well known ability to create the desired effects of hardness and toughness. Case hardening is a process in which low-carbon steel or iron is carbonized at the surface. The carburized steel part must be machined first in the soft condition, and then hardened by a case hardening treatment to create a hard outer layer. The type of heat treatment used will depend on the contents of the steel. A typical steel alloy for all-around structural purposes is composed of 0.35% carbon. For our case, we will use a chromium steel combination known as No. 5120, which is a much better quality alloy than carbon steel. The casehardened tool we seek to make will need to be able to withstand high stress impacts and have a hard durable surface to prevent the bit from breaking. Chromium-steel No.5120 is intended to fulfill these exact specifications. The desired levels of carbon and chromium are 0.20% and 0.75%, respectively. In order to accomplish this, the correct heat treatment must be applied. A proven affordable method of casehardening is gas carbonizing. The objective of gas carbonizing is to force a flow of carbonaceous gas between the two plates. The result is a penetration of carbon in less time. The plates are heated by electricity, which allows for a more uniform carbon penetration. The best-known carbon gas used for this process is carbon monoxide because of its ability to rapidly penetrate the metal. A side effect of carbon monoxide is an oxidizing effect that might harm the casehardened metal. To avoid this, the work is packed with wood charcoal in a cylinder. It is then heat ed to the carbonizing temperature and, a current of carbon dioxide is infused into the cylinder. After the metal has been gas carbonized between 1650 degrees F.
