Abstract

Low carbon steel is commonly used in the coal handling industry, but has low erosion and corrosion resistance. Hence, there is often a performance decrease due to the work environment that causes erosion and corrosion. Therefore, phosphate-bonded ceramic coating is applied. Al (OH) 3 and H3PO4 are used as a base material of binder. SiC (silicon carbide) and alumina are ceramic particles which is used in this research. The heat treatment was carried out for 1 hour, 3 hours and 5 hours to determine the effect of heat treatment time on phosphate bonded ceramic characteristics. The SEM results show that the longer of the heat treatment time, the more vacancies are formed. To determine erosion resistance of ceramic coating, erosion test is conducted, and the result show that erosion rate of ceramic coating with addition of SiC particles was 7.5 mg/Kg and without SiC was 14.2 mg/Kg. To make sure of berlinite, water resistance test was carried out, because berlinite is not soluble in water and will not lose mass significantly if it’s immersed in water. The losses obtained from the water resistance test were 0.074 %. The results of the overall characterization performed showed that the longer the heat treatment time, erosion resistance and water resistance increased in the span of 1 to 5 hours.

Abstract

The frequent occurrence of unplanned maintenance of curing machine on PT XYZ car tire production line is an indication of ineffectiveness implementation of the preventive maintenance. Unplanned downtime caused increasing of lost production time and failure products during setup, and also high cost maintenance. The company must improve the effectiveness and efficiency of the maintenance system performance through updating the maintenance schedule for obtaining high availability of the machine. The purpose of this study is to identify the components which cause the failure of the curing machine and give the recommendation of the appropriate maintenance interval. Weibull distribution method is used to get the index value of fit time to failure of machine components, analyze the component failure rate, calculate the mean time between failure (MTBF) as the expected lifetime of the component. The obtained result showed that there were two critical components with an indication of the increasing failure rate, as during wear-out (β value> 1), which are namely cylinder press and EPV with an MTBF value of 89 days for cylinder presses and 231 days for EPV. The results of this study propose for updating the curing machine PM schedule. the adding pressure valve and EPV on PM activities and using the its expected lifetime as its PM interval should be considering. it will minimize unplanned downtime

Abstract

The use of bricks in both non-structural and structural construction needs to be an increase in the product produced, either by improving the quality of materials based on SNI 15-2094-2000 which explains the red brick. The purpose of this study was to analyze the effect of the Independent Variable, namely the Comparison of heating temperatures with a processing time of 12 hours, 24 hours and 36 hours, with temperatures of 300oC, 500oC and 700oC and the percentage of sand mixture of 5%, 10% and 15%. Comparison of the three independent variables will be seen what is the Optimum value of the Impact test and how the fracture that occurs is seen with SEM. The results show the smallest impact value of 264 kj / m2, and the largest value of 164 kj / m2. the calculated F value of FModel = 33.29 obtained at a significant level of 0.01 or 1% and the p value (0.0002) gives a significant value to the existing model. Whereas the Lack of Fit that occurs is 0.000199 and does not have an effect (not significant) so that the cubic mathematical model regression equation used can be accepted. Based on the interaction data and surface response to the impact strength, the effect of heating time, heating temperature and percentage of sand is very large. The point is that if the temperature and the heating time get bigger the impact test results will be even greater

Abstract

The advantages of FC 25 cast iron over steel: low-cost material, good castability, better vibration resistance and machinability. Reduction in the function of an engine component is 70% due to wear and tear (55%) and corrosion (15%). The powder nitriding process can increase the wear resistance of FC 25 material by increasing surface hardness by diffusing nitrogen atoms to the surface of the specimen at a temperature of 500-590°C. The powder nitriding produces a white layer consisting of the compound γ (Fe4N) and ε - (Fe2-3N) and has a high hardness. The influential variables are degree of availability (d.o.a) urea, holding time and temperature. Six variable variations were carried out, namely d.o.a 0,1 & d.o.a 0,2, at each holding time of 1.5, 2.5 and 3.5 hours, at a constant temperature of 550°C. The higher d.o.a urea and the longer holding time of the powder nitriding process, the white layer will be thicker and the specimens are more resistant to wear, so that this nitriding powder successfully increases the wear resistance of FC 25 material.

Abstract

This article discusses the design process of a chocolate crusher machine based on VDI 2222. The design activities begin with identifying the needs and demands of the customer until finishing the solution for the customer in the form of a design work drawing in technical documentation. The proposed method is validated in a case study of making a chocolate chopper machine design. The machine generally functions as a separator between the cocoa beans and the shell of the seeds which have been chopped in such a way as to produce the required dimensions. At the planning stage, identifying the machine's need is to be able to chop the cocoa beans until the smallest grain has a maximum dimension of 4 mm. Three alternative functions are given and assessed as a result of the conceptualization stage. Evaluation is given to the draft design by considering the material, manufacturing and maintenance aspects. At the completion stage, technical documentation in the form of detailed work drawings is produced. By setting the rotating speed, a chocolate crusher can make beans with dimensions of 2-4 mm and production capacity is about 600 kg/hour.
