Abstract

This study aims to determine the frame safety factor and the precision level of CNC plasma cutting results. The research method used is a research and development model, namely the French model. This model has 8 steps that are used to produce a CNC plasma cut design. The data analysis technique used is descriptive statistical analysis techniques derived from the results of tests conducted. Safety factor testing was conducted using the 2015 Autodesk Inventor software with a frame of 110.54 N. The precision cutting results were carried out three times using the same instrument, 20 currents with a speed of 400 mm/min, against ST 37 material with a thickness of 1.3 mm. The results showed that the frame was categorized as safe because the minimum safety factor value was 4.23 ul and the cut test results showed an average measurement with a maximum deviation of 0.3 mm, so it could be concluded that plasma CNC cutting had tolerance. rate of ± 0.3 mm.

Abstract

The thermal shock behavior of ceramic refractory materials is of particular interest. Refractory materials are submitted to local temperature gradients in service that originate thermal stresses and thermal shock damage to the material. However, thermal shock treatment on the refractory made from evaporation boat waste is not well documented. The purpose of this study is to determine the effect of thermal shock on the strength of refractory with various compositions. In this study, the refractory was made using 100% refractory cement (sample 1). For Sample 2, the refractory was made from a mixture of refactory cement and evaporation boats waste, each of 50%: 50%. Meanwhile, specimen 3 of the refractory is made from a mixture of refactory cement, evaporation boat waste, and silica sand of 40%: 50%: 10%, respectively. The Thermal shock treatment is carried out at a temperature range of 100 – 700oC for each specimen. The effect of thermal shock treatment on the mechanical properties of each refractory specimen was investigated using the impact and macrography test. Temperature variations in thermal shock have different effects on the level of impact strength on impact test specimens. The lowest strength was 0,012297735 J/mm2 at thermal shock 7000C in sample 3, and the highest impact strength was 0,03928934 J/mm2 at 400oC thermal shock temperature in sample 2. The macrographic examination shows the higher the thermal shock temperature, the greater the fracture produced when the impact test is carried out. This is because the hardness of the refractory material increases.

Abstract

The purpose of this study was to determine the effect of thermal shock and composition of graphite, kaolin (clay) on the macrostructure and impact resistance of crucible based on the waste of evaporation boats. The variation applied was composition waste of evaporation boats, graphite and kaolin 50%:25%:25%; 40%:30%:30%; 70%:15%:15%. Then the thermal shock standard temperature variation is ∆T = 100°C - 500°C. Specimens formed according to the ASTM D256 size (63.5x12.7x12.7) mm with compaction load 80 kg/cm2. Continuing the sintering process at a temperature of 1150°C holding time of 2 hours. Tests include XRD test for the waste of evaporation boats, thermal shock test, impact test and macro photo. The results showed that the highest average impact resistance is 0.01772659 Joule/mm2 with the composition of 50%: 25%: 25% without thermal shock. The lowest average resistance impact is 0.00637474 Joule/mm2 with the composition of 70%: 15%: 15% and 500°C thermal shock temperature. Based on the data, the higher treatment of temperature in thermal shock makes the lower impact resistance of the specimen.

Abstract

Evaporation boat waste contains Boron Nitride (BN) and Titanium Diboride (TiB2) so that it has electrically conductive properties with high resistance to chemicals and heat. In addition, the combination of these materials has high thermal conductivity properties with a melting point of up to 2700oC and has an oxidation resistance of up to 1000oC so it is very suitable if applied to crucibles, or refractory. The purpose of this study was to determine the effect of mixing duration on the hardness of the crucible material made from a mixture of evaporation boats waste, kaolin and fire mortar SK-34. The mixing process of evaporation boats waste, kaolin and refractory cement is carried out using a mixer machine with a duration of 30, 60 and 90 minutes. The compaction process was carried out on the mixture with a force of 40 kg/cm2 to produce a cylindrical test specimen. After seven days, the specimens were sintered at 1000oC for 2 hours. The hardness test process was carried out with the FM-800 microhardness tester machine to determine the effect of mixing duration on the final product hardness. The highest hardness of 37,2 HV was found in the final product with a mixing duration of 90 minutes. The hardness of final product is increasing with an increase in mixing duration.
